Subject: [PATCH 023/356] Update to Chromium v57 on Win (#341) and fix PyQt5
 example on Win (#325).

Fix PyQt5 support on Windows in qt.py example (#325).

Update automate.py to use --ninja-jobs also when building CEF projects.
Default jobs ninja uses is very CPU intensive and can cause much lag in OS.

+## Off-screen rendering
+
+Off-screen rendering, in short OSR, also known as windowless
+rendering, is a method of rendering pages into a memory buffer
+without creating an actual visible window. This method of
+rendering has its uses, some pluses and some minuses. Its main
+use is so that web page rendering can be integrated into apps
+that have its own rendering systems and they can draw web browser
+contents only if they are provided a pixel buffer to draw. CEF Python
+provides a few examples of integrating CEF off-screen rendering
+with frameworks such as Kivy, Panda3D and Pygame/PyOpenGl.
+
+In this tutorial it will be discussed [screenshot.py](../examples/screenshot.py)
+example which is a very basic example of off-screen rendering.
+This example creates a screenshot of a web page with viewport
+size set to 800px width and 5000px height which is an equivalent
+of scrolling down page multiple times, but you get all this in
+one single screenshot.
+
+Before running this script you must install PIL image library:
+
+```text
+pip install PIL
+```
+
+This example accepts optional arguments so that you can change
+url and viewport size. Example usage:
+
+```text
+python screenshot.py
+python screenshot.py https://github.com/cztomczak/cefpython 1024 5000
+python screenshot.py https://www.google.com/ 800 600
+```
+
+Let's discuss code in this example.
+
+To be able to use off-screen rendering mode in CEF you have to set
+[windowless_rendering_enabled](../api/ApplicationSettings.md#windowless_rendering_enabled)
+option to True, eg.:
+
+```Python
+cef.Initialize(settings={"windowless_rendering_enabled": True})
+```
+
+Do not enable this value if the application does not use off-screen
+rendering as it may reduce rendering performance on some systems.
+
+Another thing that distincts windowed rendering from off-screen
+rendering is that when creating browser you have to call SetAsOffscreen
+method on the WindowInfo object. Code from the example:
+
+```Python
+parent_window_handle = 0
+window_info = cef.WindowInfo()
+window_info.SetAsOffscreen(parent_window_handle)
+browser = cef.CreateBrowserSync(window_info=window_info,
+                                url=URL)
+```
+
+Also after creating browser it is required to let CEF know that
+viewport size is available and that OnPaint callback may be called
+(this callback will be explained in a moment) by calling
+WasResized method:
+
+```Python
+browser.WasResized()
+```
+
+Off-screen rendering requires implementing [RenderHandler](../api/RenderHandler.md#renderhandler-interface)
+which is one of client handlers and how to use them was
+explained earlier in the tutorial in the [Client handlers](#client-handlers)
+section. For basic off-screen rendering it is enough to
+implement only two methods: [GetViewRect](../api/RenderHandler.md#getviewrect)
+and [OnPaint](../api/RenderHandler.md#onpaint). In the GetViewRect
+callback information on viewport size will be provided to CEF:
+
+```Python
+def GetViewRect(self, rect_out, **_):
+    rect_out.extend([0, 0, VIEWPORT_SIZE[0], VIEWPORT_SIZE[1]])
+    return True
+```
+
+In this callback viewport size is returned via |rect_out| which
+is of type "list" and thus is passed by reference. Additionally
+a True value is returned by function to notify CEF that rectangle
+was provided.
+
+In the OnPaint callback CEF provides a [PaintBufer](../api/PaintBuffer.md#paintbuffer-object) object, which is a pixel buffer of the
+browser view. This object has [GetIntPointer](../api/PaintBuffer.md#getintpointer)
+and [GetString](../api/PaintBuffer.md#getstring) methods. In the
+example the latter method is used which returns bytes. The method
+name is a bit confusing for Python 3 users, but in Python 2 bytes
+were strings and thus the name. Here is the code:
+
+```Python
+def OnPaint(self, browser, element_type, paint_buffer, **_):
+    if element_type == cef.PET_VIEW:
+        buffer_string = paint_buffer.GetString(mode="rgba",
+                                               origin="top-left")
+        browser.SetUserData("OnPaint.buffer_string", buffer_string)
+```
+
+The |element_type| argument can be either of cef.PET_VIEW
+(main view) or cef.PET_POPUP (for drawing popup widgets like
+`<select>` element). You can see a call to [SetUserData](../api/Browser.md#setuserdata)
+which is a helper method for storing custom data associated with
+browser. This data is stored for later use when page completes
+loading. During loading of a page there are many calls to OnPaint
+callback and it is not yet known which call is the last when
+loading completes and thus image buffer is stored for later use.
+
+The screenshot example also implements another handler named
+[LoadHanadler](../api/LoadHandler.md#loadhandler-interface)
+and two of its callbacks: [OnLoadingStateChange](../api/LoadHandler.md#onloadingstatechange)
+and [OnLoadError](../api/LoadHandler.md#onloaderror). The
+OnLoadingStateChange callbacks notifies when web page loading
+completes and OnLoadError callback notifies if loading of
+page failed. When loading succeeds a function save_screenshot()
+is called which retrieves image buffer that was earlier stored
+in the browser object and then uses PIL image library to save
+it as a PNG image.
+
+At the end, it is worth noting that there is yet an another
+option for off-screen rendering named [windowless_frame_rate](../api/BrowserSettings.md#windowless_frame_rate)
+(can be passed to [CreateBrowserSync](../api/cefpython.md#createbrowsersync)),
+but is not used by this example. It sets the maximum rate
+in frames per second (fps) that OnPaint callback will be called
+
+Currently CEF requires a window manager on Linux even in off-screen
+rendering mode. On systems without screen or any input you can use
+something like [Xvfb](https://en.wikipedia.org/wiki/Xvfb) which
+performs all graphical operations in memory without showing any
+screen output. Pure headless mode is currently not supported in
+CEF, but that may change in the future. CEF currently depends on
+X11 window manager, but there are plans to support alternative
+window managers by adding Ozone support - [upstream issue #1989](https://bitbucket.org/chromiumembedded/cef/issues/1989/linux-add-ozone-support-as-an-alternative).
+
+The screenshot.py example is just a basic showcase of off-screen
+rendering features. That screenshot feature should also be possible
+to implement using windowed rendering using a normal GUI window,
+but a hidden one with height set to some very big value that it
+wouldn't fit on screen. You could then render contents of this
+window to an image. For example in Qt you can do this by using
+QImage/QPainter classes along with a call to QWidget.render().

 This callback is called for a number of different reasons, including when
 history.pushState or history.replaceState changes the reference fragment
 for the currently loaded page. In most cases you want to use
 OnLoadingStateChange. In newer CEF there is |transition_type| arg that
 provides information about the source of the navigation.

+## Change user agent string
+
+There are two options in [application settings](../api/ApplicationSettings.md)
+for changing User-Agent string: [product_version](../api/ApplicationSettings.md#product_version)
+and [user_agent](../api/ApplicationSettings.md#user_agent).
+
+The "product_version" sets the product portion of the default
+User-Agent string. If "user_agent" option is used then
+"product_version" will be ignored. For example if you set
+"product_version" to "MyProduct/10.00" then User-Agent will
+be:
+
+```text
+Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko)
+MyProduct/10.00 Safari/537.36
+```
+
+To change the whole user agent string use the "user_agent"
+option. For example set it to "MyApp/40.00 MyProduct/10.00"
+and both User-Agent HTTP header and js navigator.userAgent will be:
+
+```text
+MyAgent/20.00 MyProduct/10.00
+```
+
+Uncomment appropriate lines in [tutorial.py](../examples/tutorial.py)
+example to see the effect:
+
+```Python
+# To change user agent use either "product_version"
+# or "user_agent" options. Explained in Tutorial in
+# "Change user agent string" section.
+settings = {
+    # "product_version": "MyProduct/10.00",

+If you get such an error on Windows:
+```Text

+Traceback (most recent call last):

+(13 MB) - this is just a VC++ redistributable, not a Visual Studio
+package. For 32-bit download "vc_redist.x86.exe" file and for
+64-bit download "vc_redist.x64.exe" file.
+
+Explanation: msvcp140.dll is the DLL for the C++ runtime library.
+This dependency is added by Cython when building CEF Python
+module. It seems that Python 3.6 only ships "vcruntime140.dll"
+which is the DLL for the C runtime library.
+
+Rant: It would be nice if Guido van Rossum would stop his
+academic approach to Python development and would not have
+created Python 3 incompatibility hell. It would also be nice
+if he shipped msvcp140.dll along with vcruntime140.dll, so
+that Python 3 supports C++ extensions as well.
+
+On a side note, when using pyinstaller/py2exe tools for
+freezing application into exe then these tools should
+automatically detect the msvcp140.dll dependency and ship it
+with your application.
+
+Created [Issue #359](../../issues/359) to track this problem.

+# Contributing code
+
+This document provides information for those who would like to
+contribute new code to the CEF Python project.
+
+
+Table of contents:
+* [Requirements](#requirements)
+* [Tools](#tools)
+* [Python / Cython style guidelines](#python--cython-style-guidelines)
+* [How to debug CEF stack trace](#how-to-debug-cef-stack-trace)
+
+
+## Requirements
+
+- Pull requests should be sent for the master branch
+- Your code should follow the [style guidelines](#python--cython-style-guidelines)
+- Pull request should implement only one feature at a time, so that
+  reviewing them is easy. If you have implemented several features
+  then send them as sepearate pull requests. If not sure then ask
+  on the [Forum](https://groups.google.com/group/cefpython).
+- When adding or exposing new API you should update API docs as well
+  (the api/ directory)
+- When adding or exposing new API you should create unit tests
+  for the new functionality (the unittests/ directory). If creating
+  unit tests is not feasible or extremely difficult then you should
+  at least provide an example through [gist.github.com](https://gist.github.com/).
+- Test your code before sending PR. Run unit tests. Run various
+  examples to see if your new code didn't break them. Running unit tests,
+  hello_world.py, tutorial.py and screenshot.py examples is an absolute
+  minimum that you must do. Please try also testing examples for
+  various GUI frameworks.
+- Python code should be tested using multiple Python versions. See
+  [Issue #249](../../../issue/249) ("How to use pyenv to manage multiple
+  Python versions on Ubuntu/Mac")
+- In most cases new code should run fine on all platforms, but in
+  some cases it might be required to test on all platforms before
+  PR is merged
+- In your pull request modify also the [Authors](../Authors) file
+  to add your name and encoded email
+- If you want to update CEF version then take a look at
+  [Issue #264](../../../issues/264)("Workflow when updating CEF version").
+- Edit Python/Cython code using PyCharm IDE to see if there are any
+  style warnings for the file you're editing. If you don't see a green
+  tick in the upper-right corner of the editor's code area that means
+  something is wrong with your code and must be fixed. See the Tools
+  section below for how to configure PyCharm for editing cefpython's
+  code.
+
+
+## Tools
+
+It is recommended to use PyCharm IDE to edit Cython code. See
+[Issue #232](../../../issues/232)("Using PyCharm IDE to edit
+cefpython's Cython code") for details.
+
+
+## Python / Cython style guidelines
+
+* Try to comply with the [PEP 8 style guide](http://www.python.org/dev/peps/pep-0008/)
+* Limit all lines to a maximum of 79 characters (comments should be shorter, max 60-65 chars)
+* Do your best for the new code to be consistent with existing code base
+* Use 4 spaces for indentation
+* Commit unix-style newlines (\n)
+
+
+## How to debug CEF stack trace
+
+On Linux/Mac you can use gdb/lldb, see instructions on the
+[KB page](Knowledge-Base.md#python-crashes-with-segmentation-fault---how-to-debug).

-## Requirements
+## Pull requests
 
 - Pull requests should be sent for the master branch
-- Your code should follow the [style guidelines](#python--cython-style-guidelines)
 - Pull request should implement only one feature at a time, so that
   reviewing them is easy. If you have implemented several features
   then send them as sepearate pull requests. If not sure then ask
   on the [Forum](https://groups.google.com/group/cefpython).
-- When adding or exposing new API you should update API docs as well
-  (the api/ directory)
-  - Update or create new documents if necessary
-  - To update table of contents (TOC) in the document run the
-    tools/toc.py script
-  - To update API index run the tools/apidocs.py tool
-- When adding or exposing new API you should create unit tests
-  for the new functionality (the unittests/ directory). If creating
-  unit tests is not feasible or extremely difficult then you should
-  at least provide an example through [gist.github.com](https://gist.github.com/).
-- Test your code before sending PR. Run unit tests. Run various
-  examples to see if your new code didn't break them. Running unit tests,
-  hello_world.py, tutorial.py and screenshot.py examples is an absolute
-  minimum that you must do. Please try also testing examples for
-  various GUI frameworks.
-- Python code should be tested using multiple Python versions. See
-  [Issue #249](../../../issue/249) ("How to use pyenv to manage multiple
-  Python versions on Ubuntu/Mac")
-- In most cases new code should run fine on all platforms, but in
-  some cases it might be required to test on all platforms before
-  PR is merged
-- In your pull request modify also the [Authors](../Authors) file
-  to add your name and encoded email
-- If you want to update CEF version then take a look at
-  [Issue #264](../../../issues/264)("Workflow when updating CEF version").
-- Edit Python/Cython code using PyCharm IDE to see if there are any
-  style warnings for the file you're editing. If you don't see a green
-  tick in the upper-right corner of the editor's code area that means
-  something is wrong with your code and must be fixed. See the Tools
-  section below for how to configure PyCharm for editing cefpython's
-  code.
-
-
-## Tools
-
-It is recommended to use PyCharm IDE to edit Cython code. See
-[Issue #232](../../../issues/232)("Using PyCharm IDE to edit
-cefpython's Cython code") for details.
 
 
-## Python / Cython style guidelines
+## Code style
 
 * Try to comply with the [PEP 8 style guide](http://www.python.org/dev/peps/pep-0008/)
-* Limit all lines to a maximum of 79 characters (comments should be shorter, max 60-65 chars)
+* Limit all lines to a maximum of 79 characters (comments should
+  be shorter, max 60-65 chars)
 * Do your best for the new code to be consistent with existing code base
 * Use 4 spaces for indentation
 * Commit unix-style newlines (\n)
 
 
-## How to debug CEF stack trace
+## Code warnings in PyCharm
+
+Edit Python/Cython code using PyCharm IDE to see if there are any
+style warnings for the file you're editing. If you don't see a green
+tick in the upper-right corner of the editor's code area that means
+something is wrong with your code and must be fixed. See
+[Issue #232](../../../issues/232)("Using PyCharm IDE to edit
+cefpython's Cython code") for details.
+
+
+## Test your code
+
+Test your code before sending PR. Run unit tests. Run various
+examples to see if your new code didn't break them. Running unit tests,
+hello_world.py, tutorial.py and screenshot.py examples is an absolute
+minimum that you must do. Please try also testing examples for
+various GUI frameworks.
+
+Pure Python code should be tested using multiple Python versions. See
+[Issue #249](../../../issue/249) ("How to use pyenv to manage multiple
+Python versions on Ubuntu/Mac").
+
+
+## API docs
+
+When adding or exposing new API you should update API docs as well
+(the api/ directory):
+
+- Update or create new documents if necessary
+- To update table of contents (TOC) in the document run the
+  tools/toc.py script
+- To update API index run the tools/apidocs.py script
+
+
+## Unit tests
+
+When adding or exposing new API you should create unit tests
+for the new functionality (the unittests/ directory).If creating
+unit tests is not feasible or extremely difficult then you should
+at least provide an example through [gist.github.com](https://gist.github.com/).
+
+CEF imposes some limits on the structure of unit tests. Most of
+CEF API requires that CEF is initialized before its API is used.
+So each test must start with a call to cef.Initialize, however
+CEF can be initialized only once during app's lifetime. The way
+python unittest module works doesn't allow to define for example
+test methods named "test_1_initialize", "test_2_some", "test_3_shutdown",
+after doing so some strange things happen (maybe unittest is
+running these methods in separate threads). So with these
+restrictions the way it works currently is that there is ongle
+single method named "test_main" in which muliple sub-tests are
+run. A function named "subtest_message" was defined to be able
+to output results of the multiple subtests that are running inside
+the "test_main" method.
+
+In main_test.py there were implemented automated checks in handlers
+and in the external object. When class (handler or external)
+defines a property that ends with "_True" or "_False" then it will
+be automatically checked  whether it asserts to these values just
+before CEF shutdown. There is one limitation for these type
+of automatic asserts - its values should be set first
+before executing normal kind of asserts, so that they are reported
+correctly, otherwise you might see misleading reports about failed
+asserts.
+
+CEF Python's unit tests are run using a special script named
+_test_runner.py. This script implements a way to run all unit
+tests (by default with no arguments passed) and also implements
+some special features like Isolated Tests along with some other
+minor features for CEF special case. An isolated test is run
+using a separate Python intepreter (a separate process). To mark
+a Test class an isolated test just append "_IsolatedTest" in
+its name. Isolated tests are required for running CEF tests
+properly. The _test_runner.py script allows to run multiple CEF
+isolated tests in one execution. You can define multiple
+test classes like "MyTest1_IsolatedTest" and "MyTest2_IsolatedTest"
+in one file, but keep in mind that you can define only a single
+test method in these classes as explained earlier. Each of such
+tests should have logic to initialize and shutdown CEF properly.
+
+
+## Platforms
+
+In most cases new code should run fine on all platforms, but in
+some cases it might be required to test on all platforms before
+PR is merged.
+
+## Authors
+
+In your pull request modify also the [Authors](../Authors) file
+to add your name and encoded email.
+
+## Updating CEF version
 
-On Linux/Mac you can use gdb/lldb, see instructions on the
-[KB page](Knowledge-Base.md#python-crashes-with-segmentation-fault---how-to-debug).
+If you want to update CEF version then take a look at
+[Issue #264](../../../issues/264)("Workflow when updating CEF version").

-## Message loop
-
-Message loop is a programming construct that waits for and
-dispatches events or messages in a program. All desktop GUI
-programs must run some kind of message loop. The hello_world.py
-example doesn't depend on any third party GUI framework and thus
-can run CEF message loop directly by calling cef.MessageLoop().
-However in other examples that embed CEF browser with GUI frameworks
-such as Qt/wxPython/Tkinter you can't call cef.MessageLoop(), because
-these frameworks run a message loop of its own. For such cases CEF
-provides cef.MessageLoopWork() which is for integrating CEF message
-loop into existing application message loop. Usually
-cef.MessageLoopWork() is called in a 10ms timer.
-
-**Performance**
-
-Calling cef.MessageLoopWork() in a timer is not the best performant
-way to run CEF message loop, also there are known bugs on some
-platforms when calling message loop work in a timer. There are two
-options to increase performance depending on platform. On Windows
-use a multi-threaded message loop for best performance. On Mac use
-an external message pump for best performance.
-
-**Windows: multi-threaded message loop**
-
-On Windows for best performance a multi-threaded message loop should
-be used instead of cef.MessageLoopWork() or external message pump. To do
-so, set ApplicationSettings.[multi_threaded_message_loop](../api/ApplicationSettings.md#multi_threaded_message_loop)
-to True and run a native message loop in your app. Don't call CEF's
-message loop. Create browser using `cef.PostTask(cef.TID_UI, cef.CreateBrowserSync, ...)`.
-Note that when using multi-threaded message loop, CEF's UI thread
-is no more application's main thread, and that makes it a bit harder
-to correctly use CEF API. API docs explain on which threads a function
-may be called and in case of handlers' callbacks (and other interfaces)
-it is stated on which thread a callback will be called. See also

-option for running an external message pump that you should use for
-best performance and to get rid of some bugs that appear when using

-This option is currently marked experimental as it wasn't yet fully

Subject: [PATCH 085/356] Remove Frame.GetProperty/SetProperty deprecated
 methods from API docs.

This methods are not implemented. I guess they are remainings from
CEF 1 which ran using single process mode and getting/setting properties
worked synchronously. But in CEF 3 which runs in multi-process mode
you can do this only asynchronusly, you can use already implemented
js<>py communication layer for that.

+## Package app
+
+This is an example of using [PyInstaller](http://www.pyinstaller.org/)
+packager to build executable from one of CEF Python's examples
+(wxpython.py). Only Windows platform is currently supported.
+
+To install required packages type:
+```
+pip install --upgrade pyinstaller pycrypto
+```
+
+To package example type:
+```
+python pyinstaller.py
+```
+
+
+## When it succeeds
+
+If packaging succeeds you should see "dist/cefapp/" directory open
+in explorer on Windows. In there you will find "cefapp.exe" executable
+that you can launch.
+
+![cefapp directory](screenshots/cefapp_directory.jpg)
+
+
+## Fatal error
+
+If there is a "Fatal Error!" message box appearing when running app
+then see the next section for how to debug app.
+
+![Fatal Error](screenshots/cefapp_fatal_error.jpg)
+
+
+## Debug app
+
+In case of a fatal error to debug app pass "--debug" flag when
+packaging app:
+
+```
+python pyinstaller.py --debug
+```
+
+After packaging completes on Windows it will open a new CMD window
+and run the cefapp.exe inside it. You should see detailed logs
+in console like these:

 ## Build executable
 
-There are no official examples for building executable using
-python packaging tools, however some resources and tips are
-available, see these issues in the tracker:
+Currently there is available [PyInstaller example](../examples/pyinstaller/README-pyinstaller.md)
+for building executable, by default it packages the wxpython.py example.
 
-* Pyinstaller - see [Issue #135](../../../issues/135)
+There are many more Python packagers available, however no
+official examples are provided for these. See the following
+issues in the tracker for all available packagers:
+
+* cx_Freeze - see [Issue #338](../../../issues/338)
 * py2exe - see [Issue #35](../../../issues/35)
 * py2app - see [Issue #337](../../../issues/337)
-* cx_Freeze - see [Issue #338](../../../issues/338)

-## Introduction
-
-By default if DPI awareness is not enabled in application, then OS performs display scaling. That causes text to look fuzzy on high DPI displays. The solution is to enable DPI awareness and use the ApplicationSettings.`auto_zooming` option. High DPI support is available only on Windows.
-
-Enabling High DPI support in app can be done by embedding a DPI awareness xml manifest in executable (see [Issue #112](../issues/112) comment #2), or by calling the `DpiAware.SetProcessDpiAware` method. Embedding xml manifest is the most reliable method. There is also an another way by writing registry key, but we won't discuss this method here.
-
-The downside of calling `SetProcessDpiAware` is that scrollbar in CEF browser is very small. This is because DPI awareness was set too late, after executable and the CEF dll was loaded. To fix that embed DPI awareness xml manifest in the .exe file.
 
-Additionally you have to set the ApplicationSettings.`auto_zomming` option to "system_dpi". This will cause browser content to be zoomed automatically using system DPI settings. On Win7 these can be set in: Control Panel > Appearance and Personalization > Display.
+## Introduction
 
-When cefpyhon detects that application is DPI aware, it will automatically set ApplicationSettings."auto_zooming" to "system_dpi". User can manually enable DPI awareness in application by going to .exe properties > Compatibility tab > and checking the box labeled "Disable display scaling on high DPI settings". If you wish to not enable auto zooming in such case then set "auto_zooming" to an empty string.
+By default if DPI awareness is not enabled in application, then OS performs display scaling. That causes text to look blurry on high DPI displays. To resolve this you have to

+Enabling High DPI support in app can be done by embedding a DPI awareness xml manifest in both main executable and subprocess executable (see [Issue #112](../issues/112) comment #2), or by calling the `cef.DpiAware.EnableHighDpiSupport` method.

 """
- Simple SDL2 / cefpython3 example.
+Example of embedding CEF browser using PySDL2 library.
 
- Requires pysdl2 (and SDL2 library).
- 
- Tested configurations:
- - SDL2 2.0.5 with PySDL2 0.9.3 on Fedora 25 (x86_64)
- - SDL2 with PySDL2 0.9.5 on Ubuntu 14.04
+This example is incomplete, see "Missing functionality" section
+further down. Pull requests for the missing functionality are welcome.
 
- Install instructions.
- 
- 1. Install SDL libraries for your OS, e.g:
+Requires PySDL2 and SDL2 libraries.
  
-    Fedora:
-    
-        sudo dnf install SDL2 SDL2_ttf SDL2_image SDL2_gfx SDL2_mixer
-        
-    Ubuntu:
-    
-        sudo apt-get install libsdl2-dev
-
- 2. Install PySDL via PIP:
+Tested configurations:
+- Fedora 25: SDL2 2.0.5 with PySDL2 0.9.3
+- Ubuntu 14.04: SDL2 with PySDL2 0.9.6
 
-    sudo pip2 install PySDL2
+Install instructions:
+1. Install SDL libraries for your OS, e.g:
+   - Fedora: sudo dnf install SDL2 SDL2_ttf SDL2_image SDL2_gfx SDL2_mixer
+   - Ubuntu: sudo apt-get install libsdl2-dev
+2. Install PySDL2 using pip package manager:
+   pip install PySDL2
  
- Event handling:
- 
- Where possible SDL2 events are mapped to CEF ones. Not all keyboard
- modifiers are handled in this example but these could be
- added by the reader (if desired). Modifiers that do not work
- for example:
- 
- - Ctrl
- - Mouse dragging
- - Marking text inputs with the shift key
- 
- Due to SDL2's lack of GUI widgets there are no GUI controls
- for the user. However, as an exercise this example could
- be extended by create some simple SDL2 widgets. An example of
- widgets made using PySDL2 can be found as part of the Pi
- Entertainment System at:
- https://github.com/neilmunday/pes/blob/master/lib/pes/ui.py
+Missing functionality:

+### Building old unsupported version of Chromium 
+
+When building an old version of Chromium you may get into issues.
+For example as of this writing the latest CEF Python version is
+v57, but current support Chromium version is v64. Now when building
+v57 you may encounter issues since Chromium build tools had
+many updates since v57. You have to checkout depot_tools from the
+revision when Chromium v57 was released. When running automate.py
+tool the depot_tools repository resides in `build_dir/depot_tools/`
+directory. If you didn't run automate.py then you can find repository
+url in automate-git.py script. For example for v57 release to checkout
+an old revision of depot_tools you can use this command:
+
+```
+git checkout master@{2017-04-20}
+```
+
+After that set `DEPOT_TOOLS_UPDATE=0` environment variable and then
+run automate.py tool.

 CEF Python depends on CEF and API breaks are inevitable when updating

-v31 release. Until it's done go to go to the [GitHub Releases](../../../releases)

 Due to unavoidable changes in API it is recommended for your setup
 scripts that use for example PIP to install the cefpython3 package,
 to hardcode the cefpython version string. If for example using PIP's
 requirements.txt file then list the cefpython3 package in the
-following format: `cefpython3 == 31.2`.

-
-Some modifications were applied for CEF Python specific use case.
-There is a patch file with the same name as this script that contains
-differences from the original file.
-
--------------------------------------------------------------------------------
-
-Usage: automate-git.py [options]
-
- This utility implements automation for the download, update, build and
-distribution of CEF.
-
-Options:
-  -h, --help            show this help message and exit
-  --download-dir=DIR    Download directory with no spaces [required].
-  --depot-tools-dir=DIR
-                        Download directory for depot_tools.
-  --depot-tools-archive=DEPOTTOOLSARCHIVE
-                        Zip archive file that contains a single top-level
-                        depot_tools directory.
-  --branch=BRANCH       Branch of CEF to build (trunk, 1916, ...). This will
-                        be used to name the CEF download directory and to
-                        identify the correct URL if --url is not specified.
-                        The default value is trunk.
-  --url=URL             CEF download URL. If not specified the default URL
-                        will be used.
-  --chromium-url=CHROMIUMURL
-                        Chromium download URL. If not specified the default
-                        URL will be used.

-  --chromium-checkout=CHROMIUMCHECKOUT
-                        Version of Chromium to checkout (Git branch/hash/tag).
-                        This overrides the value specified by CEF in
-                        CHROMIUM_BUILD_COMPATIBILITY.txt.
-  --force-config        Force creation of a new gclient config file.
-  --force-clean         Force a clean checkout of Chromium and CEF. This will
-                        trigger a new update, build and distribution.
-  --force-clean-deps    Force a clean checkout of Chromium dependencies. Used
-                        in combination with --force-clean.

+
+-------------------------------------------------------------------------------
+
+Usage: automate-git.py [options]
+
+ This utility implements automation for the download, update, build and
+distribution of CEF.
+
+Options:
+  -h, --help            show this help message and exit
+  --download-dir=DIR    Download directory with no spaces [required].
+  --depot-tools-dir=DIR
+                        Download directory for depot_tools.
+  --depot-tools-archive=DEPOTTOOLSARCHIVE
+                        Zip archive file that contains a single top-level
+                        depot_tools directory.
+  --branch=BRANCH       Branch of CEF to build (trunk, 1916, ...). This will
+                        be used to name the CEF download directory and to
+                        identify the correct URL if --url is not specified.
+                        The default value is trunk.
+  --url=URL             CEF download URL. If not specified the default URL
+                        will be used.
+  --chromium-url=CHROMIUMURL
+                        Chromium download URL. If not specified the default
+                        URL will be used.
+  --checkout=CHECKOUT   Version of CEF to checkout. If not specified the most
+                        recent remote version of the branch will be used.
+  --chromium-checkout=CHROMIUMCHECKOUT
+                        Version of Chromium to checkout (Git branch/hash/tag).
+                        This overrides the value specified by CEF in
+                        CHROMIUM_BUILD_COMPATIBILITY.txt.
+  --chromium-channel=CHROMIUMCHANNEL
+                        Chromium channel to check out (canary, dev, beta or
+                        stable). This overrides the value specified by CEF in
+                        CHROMIUM_BUILD_COMPATIBILITY.txt.
+  --chromium-channel-distance=CHROMIUMCHANNELDISTANCE
+                        The target number of commits to step in the channel,
+                        or 0 to use the newest channel version. Used in
+                        combination with --chromium-channel.
+  --force-config        Force creation of a new gclient config file.
+  --force-clean         Force a clean checkout of Chromium and CEF. This will
+                        trigger a new update, build and distribution.
+  --force-clean-deps    Force a clean checkout of Chromium dependencies. Used
+                        in combination with --force-clean.
+  --dry-run             Output commands without executing them.
+  --dry-run-platform=DRYRUNPLATFORM
+                        Simulate a dry run on the specified platform (windows,
+                        macosx, linux). Must be used in combination with the
+                        --dry-run flag.
+  --force-update        Force a Chromium and CEF update. This will trigger a
+                        new build and distribution.
+  --no-update           Do not update Chromium or CEF. Pass --force-build or
+                        --force-distrib if you desire a new build or
+                        distribution.
+  --no-cef-update       Do not update CEF. Pass --force-build or --force-
+                        distrib if you desire a new build or distribution.
+  --force-cef-update    Force a CEF update. This will cause local changes in
+                        the CEF checkout to be discarded and patch files to be
+                        reapplied.
+  --no-chromium-update  Do not update Chromium.
+  --no-depot-tools-update
+                        Do not update depot_tools.
+  --fast-update         Update existing Chromium/CEF checkouts for fast
+                        incremental builds by attempting to minimize the
+                        number of modified files. The update will fail if
+                        there are unstaged CEF changes or if Chromium changes
+                        are not included in a patch file.
+  --force-patch-update  Force update of patch files.
+  --resave              Resave patch files.
+  --log-chromium-changes
+                        Create a log of the Chromium changes.
+  --force-build         Force CEF debug and release builds. This builds
+                        [build-target] on all platforms and chrome_sandbox on
+                        Linux.
+  --no-build            Do not build CEF.
+  --build-target=BUILDTARGET
+                        Target name(s) to build (defaults to "cefclient").
+  --build-tests         Also build the test target specified via --test-
+                        target.
+  --no-debug-build      Don't perform the CEF debug build.
+  --no-release-build    Don't perform the CEF release build.
+  --verbose-build       Show all command lines while building.
+  --build-failure-limit=BUILDFAILURELIMIT
+                        Keep going until N jobs fail.
+  --build-log-file      Write build logs to file. The file will be named
+                        "build-[branch]-[debug|release].log" in the download
+                        directory.
+  --x64-build           Create a 64-bit build.
+  --arm-build           Create an ARM build.
+  --run-tests           Run the ceftests target.
+  --no-debug-tests      Don't run debug build tests.
+  --no-release-tests    Don't run release build tests.
+  --test-target=TESTTARGET
+                        Test target name to build (defaults to "ceftests").
+  --test-prefix=TESTPREFIX
+                        Prefix for running the test executable (e.g. `xvfb-
+                        run` on Linux).
+  --test-args=TESTARGS  Arguments that will be passed to the test executable.
+  --force-distrib       Force creation of a CEF binary distribution.
+  --no-distrib          Don't create a CEF binary distribution.
+  --minimal-distrib     Create a minimal CEF binary distribution.
+  --minimal-distrib-only

 List of threads in the Browser process:
 * cef.TID_UI: The main thread in the browser. This will be the same as the main application thread if cefpython.Initialize() is called with a ApplicationSettings.multi_threaded_message_loop value of false. Do not perform blocking tasks on this thread. All tasks posted after CefBrowserProcessHandler::OnContextInitialized() and before CefShutdown() are guaranteed to run. This thread will outlive all other CEF threads.
 * cef.TID_DB: Used to interact with the database.

 The RequestHandler.[OnBeforeBrowse](../api/RequestHandler.md#onbeforebrowse)
 callback has a new param `user_gesture`.
 
+
+## v66+ Window transparency changes
+
+1. OSR windows (off-screen rendering, also known as windowless) are now
+transparent by default. You can control its transperency with
+ApplicationSettings.[background_color](../api/ApplicationSettings.md#background_color) and BrowserSettings.[background_color](../api/BrowserSettings.md#background_color) options.
+The WindowInfo.`SetTransparentPainting` method is now deprecated. Calling
+it with True will do nothing, and calling it with False **will result
+in exception**.
+
+2. It is now possible to have
+transparent windows also in **windowed mode**. This seems to be working
+only on Linux (got it working on Fedora with just a change in window setting).

+### GetImage
+
+| | |
+| --- | --- |
+| __Return__ | tuple(bytes buffer, int width, int height) |
+
+Currently works only on Linux (Issue [#427](../../../issues/427)).
+
+Get browser contents as image. Only screen visible contents are returned.
+
+Returns an RGB buffer which can be converted to an image
+using PIL library with such code:
+
+```py
+from PIL import Image, ImageFile
+buffer_len = (width * 3 + 3) & -4
+image = Image.frombytes("RGB", (width, height), data,
+                         "raw", "RGB", buffer_len, 1)
+ImageFile.MAXBLOCK = width * height
+image.save("image.png", "PNG")
+```

-## ImportError: DLL load failed (Windows)
-
-If you get such an error on Windows:
-```Text
-import cefpython3
-Traceback (most recent call last):
-  File "<stdin>", line 1, in <module>
-  File "C:\Python3\lib\site-packages\cefpython3\__init__.py", line 59, in <module>
-    from . import cefpython_py36 as cefpython
-ImportError: DLL load failed: The specified module could not be found.
-```
-
-Then most probably this is caused, because you are missing
-"msvcp140.dll" dependency (for Python 3.5/3.6/3.7 for example). This
-is a dependency for Python C++ extensions (eg. cefpython_py36.pyd
-depends on it). For Python 3.5/3.6/3.7 to fix this download
-[Visual C++ Redistributable for VS2015](https://www.microsoft.com/en-us/download/details.aspx?id=52685)
-(13 MB) - this is just a VC++ redistributable, not a Visual Studio
-package. For 32-bit download "vc_redist.x86.exe" file and for
-64-bit download "vc_redist.x64.exe" file.
-
-Explanation: msvcp140.dll is the DLL for the C++ runtime library.
-This dependency is added by Cython when building CEF Python
-module. It seems that Python 3.6 only ships "vcruntime140.dll"
-which is the DLL for the C runtime library.
-
-On a side note, when using pyinstaller/py2exe tools for
-freezing application into exe then these tools should
-automatically detect the msvcp140.dll dependency and ship it
-with your application.
-
-Created [Issue #359](../../../issues/359) to track this problem.

Subject: [PATCH 215/356] Further changes to message loop issues on Mac (#442).

Minor fix to CefAppProtocol implementation, see CEF Forum
topic for details.

Updated Qt example so that message loop work is not
called in a timer when message pump is enabled. This
is not required.

In wxPython apps it is still required to enable both
message pump and message looper timer work.

+# AccessibilityHandler (interface)
+
+This handler is for use only with off-screen rendering enabled.
+See [RenderHandler](RenderHandler.md) for details.
+
+Implement this interface to receive accessibility notification when
+accessibility events have been registered. The methods of this class will
+be called on the UI thread.
+
+Callbacks in this interface are not associated with any specific browser,
+thus you must call cefpython.[SetGlobalClientHandler] or 
+SetGlobalClientCallback() to use them. The callbacks names were prefixed
+with "`_`" to distinguish this special behavior.
+
+For an example of how to implement handler see [cefpython](cefpython.md).CreateBrowser(). For a list of all handler interfaces see [API > Client handlers](API#Client_handlers).

+Description from upstream CEF:
+> Set accessibility state for all frames. |accessibility_state| may be
+> default, enabled or disabled. If |accessibility_state| is STATE_DEFAULT
+> then accessibility will be disabled by default and the state may be further
+> controlled with the "force-renderer-accessibility" and

+> |accessibility_state| is STATE_ENABLED then accessibility will be enabled.
+> If |accessibility_state| is STATE_DISABLED then accessibility will be
+> completely disabled.
+>
+> For windowed browsers accessibility will be enabled in Complete mode (which
+> corresponds to kAccessibilityModeComplete in Chromium). In this mode all
+> platform accessibility objects will be created and managed by Chromium's
+> internal implementation. The client needs only to detect the screen reader

+Set client handler object (class instance). Its members will be inspected.
+Private methods that are not meant to be callbacks should have their names
+prepended with two underscores. Methods with single underscore or no

+> Windows) and is updated periodically by Chrome's component updater service.
+> Must be called in the browser process after the context has been initialized.

-It is required to install X11 error handlers on Linux, otherwise
-you will see 'BadWindow' errors happening - sometimes randomly -
-which will cause application to terminate. Since v56+ x11 error
-handlers are installed automatically by default during the call
-to cef.Initialize(). However sometimes that is not enough like
-for example in the wxpython.py example which requires the x11
-error handlers to be installed manually after wx was initialized,
-and that is because wx initialization had reset x11 error handlers
-that were installed earlier during cef initialization (Issue [#334](../../../issues/334)).
+## v49+ Build instructions and build tools
 
-You can install X11 error handlers by calling:
-```
-WindowUtils = cef.WindowUtils()
-WindowUtils.InstallX11ErrorHandlers()
-```
+There were many changes in regards to building CEF and CEF Python.
+There are now new tools in the tools/ root directory that fully
+automate building CEF and CEF Python. CEF Python now provides
+upstream CEF prebuilt binaries and libraries on GitHub Releases
+tagged eg. "v49-upstream". With these binaries you can build
+CEF Python from sources in less than 10 minutes. See the new
+[Build instructions](Build-instructions.md) document.

+## v49: GPU acceleration should be disabled on Windows XP
 
-## v50+ Set window bounds on Linux
+On XP you should disable GPU acceleration by setting the `--disable-gpu`
+and `--disable-gpu-compositing` switches. These switches can
+be passed programmatically to `cef.Initialize`, see
+[api/Command Line Switches](../api/CommandLineSwitches.md).
 
-It is now required to set window bounds during window "resize",
-"move" and "configure" events on Linux. You can do so by calling:
 
-```
-browser.SetBounds(x, y, width, height)
-```
+## v49 (Win) Handlers' callbacks and other interfaces
 
-API ref: Browser.[SetBounds()](../api/Browser.md#setbounds)
+In v49.0 release for Windows all handlers'
+callbacks and other interfaces such as
+CookieVisitor, StringVisitor and WebRequestClient, are now called
+using keyword arguments (Issue [#291](../../../issues/291)).
+This will cause many of existing code to break. This is how you
+should declare callbacks using the new style:
+
+```
+def OnLoadStart(self, browser, **_):
+	pass
 
+def OnLoadStart(self, **kwargs):
+	browser = kwargs["browser"]
+```
 
-## v50+ Notify CEF on move or resize events
+In the first declaration you see that only one argument is
+declared, the browser, the others unused will be in the "_"
+variable (the name of the variable is so that PyCharm doesn't
+warn about unused variable).
 
-It is required to notify the browser on move or resize events
-so that popup widgets (e.g. \<select\>) are displayed in the correct
-location and dismissed when the window moves. Also so that
-drag & drop areas are updated accordingly.
+Even if you specify and use all arguments, always add the
+unused kwargs (`**_`) at the end:
 
 ```
-browser.NotifyMoveOrResizeStarted()
+def OnLoadStart(self, browser, frame, **_):
+	pass
 ```
 
-API ref: Browser.[NotifyMoveOrResizeStarted()](../api/Browser.md#notifymoveorresizestarted)
-
+This will be handy in the future, in a case when upstream CEF
+adds a new argument to the API, your code won't break. When
+an argument is removed in upstream CEF API, if it's possible
+CEF Python will try to keep backward compatibility by
+emulating behavior of the old argument.
 
-## v50+ Keyboard focus issues on Linux
+In case of OnLoadStart, when you've used "browser" and "frame"
+names for the arguments, your code won't break. However in
+many other callbacks, where you've used argument names that
+differed from how they were named in API docs, your code will
+break. Also argument names were changed from camelCase
+to underscores. For example the OnLoadEnd callback has renamed
+the `httpStatusCode` argument to `http_code`. So in this case
+your code will definitely break, unless you've also used
+"http_code" for argument name.
 
-There several keyboard focus issues on Linux since CEF library
-replaced GTK library with X11 library. Most of these issues are
-fixed in examples by calling SetFocus in LoadHandler.OnLoadStart
-during initial app loading and/or by calling SetFocus in
-FocusHandler.OnGotFocus. This keyboard focus issues need to be
-fixed in usptream CEF. For more details see Issue [#284](../../../issues/284).
 
+## v49+ High DPI support on Windows
 
-## v50+ Windows XP and Vista are no more supported
+It is recommended to embed a DPI awareness manifest in both the main
+process and the subprocesses (the subprocess.exe executable) instead
+of calling `DpiAware`.[SetProcessDpiAware](../api/DpiAware.md#setprocessdpiaware)
+which sets DPI awareness only for the main process.
 
-CEF Python v31.2 was the last version to support Windows XP.
-This is due to Chromium/CEF dropping XP support, last version
-that supported XP was CEF v49.
+The `ApplicationSettings`.[auto_zooming](../api/ApplicationSettings.md#auto_zooming)
+option has a default value of an empty string now. Previously the
+default was "system_dpi". When enabling High DPI support you should
+set it to "system_dpi" explicitilly.
 
+Note that `DpiAware`.[CalculateWindowSize](../api/DpiAware.md#calculatewindowsize)
+does not handle all DPI settings (e.g. 132% on Windows 10).
+In newer CEF Python there is available `DpiAware`[Scale](../api/DpiAware.md#scale)
+which is more reliable and can handle all DPI resolutions. You can copy see
+its implementation in `src/dpi_aware_win.pyx`.

+## Remote debugging with Google Chrome instance
+
+Remote debugging is enabled by default and is configurable using

+When launching app you can see in console log the random port that
+was generated:

+DevTools listening on ws://127.0.0.1:63967/devtools/browser/c52ad9ad-bf40-47d1-b2d1-be392d536a2b
+```
+
+You can debug remotely in two ways:
+
+1. Debug with CEF devtools. Open the `http://127.0.0.1:port` url
+   (replace port with e.g. 63967 in our case) in a Google Chrome
+   browser. You will see a list of CEF browser instances running
+   which you can debug with DevTools.
+   This way of debugging has the same sets of features as opening DevTools
+   popup via `Browser.ShowDevTools` method or using the "Show DevTools"
+   option from mouse context menu in a CEF app. CEF DevTools has some
+   limits, not all features of Google Chrome DevTools do work. There
+   is another way to remotely debug that can workaround these limits,
+   see the point 2 below.
+
+2. If some features don't work when debugging with CEF devtools you can
+   use dedicated DevTools for Node in Google Chrome browser. For example
+   as of CEF v70 the devtools feature "Save as HAR file" doesn't work,
+   however it works with dedicated DevTools for Node. Follow these steps
+   to use dedicated DevTools for Node with CEF:
+
+   1. In Google Chrome browser open `chrome://inspect` url and click
+      "Open dedicated DevTools for Node"
+   2. Add `localhost:1234` connection and close the popup window
+   3. Set `ApplicationSettings.remote_debugging_port` to `1234` and
+      run your app
+   4. Refresh the `chrome://inspect` page in Google Chrome browser
+   5. You should see a new target on the Remote Target list. Click
+      "inspect" link for this target.

 ## Introduction
 
-CEF Python is a BSD-licensed open source project founded by Czarek Tomczak (hire me! see my [resume](https://drive.google.com/file/d/17xmoT5Z_zTHkVclqPzrs2aAV64Uiu7fh/view)) in 2012 and is based on Google Chromium and the
-[CEF Framework](https://bitbucket.org/chromiumembedded/cef)

+CEF Python is an open source project founded by [Czarek Tomczak](https://drive.google.com/file/d/17xmoT5Z_zTHkVclqPzrs2aAV64Uiu7fh/view)
+(available for contract work) in 2012 to provide Python bindings for the
+[Chromium Embedded Framework](https://bitbucket.org/chromiumembedded/cef) (CEF). The Chromium project focuses mainly on Google Chrome application
 development while CEF focuses on facilitating embedded browser use cases
 in third-party applications. Lots of applications use CEF control, there are
 more than [100 million CEF instances](http://en.wikipedia.org/wiki/Chromium_Embedded_Framework#Applications_using_CEF)
-installed around the world. [Examples of embedding](examples/README-examples.md)
-Chrome browser are available for many popular GUI toolkits including:
-wxPython, PyGTK, PyQt, PySide, Kivy, Panda3D and PyGame/PyOpenGL.
-
-There are many use cases for CEF. You can embed a web browser control
-based on Chromium with great HTML 5 support. You can use it to create
-a HTML 5 based GUI in an application, this can act as a replacement for
-standard GUI toolkits such as wxWidgets, Qt or GTK. In such case to
-communicate between Python<>Javascript use [javascript bindings](docs/Tutorial.md#javascript-integration)
-or embed an internal web server and talk using http requests. You
-can render web content off-screen in applications that use custom
-drawing frameworks. You can use it for automated testing of existing
-applications. You can use it for web scraping or as a web crawler,
-or other kind of internet bots.
+installed around the world. There are numerous use cases for CEF:
+1. Use it as a modern HTML5 based rendering engine that can act as a replacement
+   for classic desktop GUI frameworks. Think of it as Electron for Python.
+2. Embed a web browser widget in a classic Qt / GTK / wxPython desktop
+application
+3. Render web content off-screen in applications that use custom drawing frameworks
+4. Use it for automated testing of web applications with more advanced capabilities
+   than Selenium web browser automation due to
+   CEF low level programming APIs
+5. Use it for web scraping, as a web crawler or other kind of internet bots
+
+CEF Python also provides examples of embedding CEF for many Python GUI
+frameworks such as PyQt, wxPython, PyGTK, PyGObject, Tkinter, Kivy, Panda3D,
+PyGame, PyOpenGL, PyWin32, PySide and PySDL2.

+## Seeking new sponsors
+
+CEF Python is seeking companies to sponsor further development of the project.
+There are many proposals for new features submitted in the issue tracker. Most
+notable are:
+
+* Monthly releases with latest Chromium
+* An automated build system similar to upstream CEF Spotify Automated Builds
+* ARM and Android support
+* Multi-threaded support for increased performance
+* Proprietary codecs support in build tools: H264, H265,AC3, EAC3, MPEG-4
+* More CEF API exposed, only about 50% is exposed so far
+* Hundreds of new settings and Chromium preferences not yet exposed
+* Easier integration with popular GUI toolkits in just a few lines of code
+  and support for more third party GUI frameworks
+* More examples of implementing various advanced features and more snippets
+  as well
+
+If your company would like to sponsor CEF Python development efforts then
+please contact
+[Czarek](https://drive.google.com/file/d/17xmoT5Z_zTHkVclqPzrs2aAV64Uiu7fh/view).
+Long term sponsorships are welcome and Czarek is open to ideas about
+the project. He would love to spend more time on developing this project,
+but he can't afford doing so in his free time. Currently there is no company
+supporting this project actively on a daily basis.

+## GIL
+
+In the pxd file, functions should be defined as "nogil" to avoid
+deadlocks when calling CEF functions. In the pyx file the call must
+use the "with nogil" statement.
+
+From [Cython's documentation](http://docs.cython.org/src/userguide/external_C_code.html#acquiring-and-releasing-the-gil):
+
+> Note that acquiring the GIL is a blocking thread-synchronising operation,
+> and therefore potentially costly. It might not be worth releasing the GIL
+> for minor calculations. Usually, I/O operations and substantial computations
+> in parallel code will benefit from it.
+
+Revision [ec1ce78](https://github.com/cztomczak/cefpython/commit/ec1ce788373bb9e0fd2cedd71e900c3877e9185a) removes the GIL lock from the
+following calls: Initialize(), Shutdown(), CreateBrowserSync(),
+SetOsModalLoop(), QuitMessageLoop(), CefExecuteProcess(). There still
+might be some more functions from which the GIL lock should be removed.

Subject: [PATCH 335/356] Update int range detection for Python 3 (#603)

* Update int range detection for Python 3

Python 3 unified ints and longs into a single int type. The long type
is still available in Cython as an alias to int.

* Update javascript_bindings.pyx

* Update process_message_utils.pyx

Subject: [PATCH 338/356] Add support for Python 3.8 and Upgrade Cython (#594)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes: https://github.com/cztomczak/cefpython/issues/546

Had to include harfbuzz manually as newer Pango change this.
See:
    https://github.com/eiskaltdcpp/eiskaltdcpp/issues/413
    https://gitlab.gnome.org/GNOME/pango/-/issues/387

Also had to add `-Wno-deprecated-declarations` to get this to compile because
of the following errors that didn't seem to be coming from this code directly:

    warning: ‘GTimeVal’ is deprecated: Use 'GDateTime' instead
    warning: ‘GTypeDebugFlags’ is deprecated

Subject: [PATCH 342/356] Fix build_distrib.py script for Python 2.7 and Python
 3.4 (latest pip versions are broken with these old Pythons).

Fix screenshot.py example sometimes failing.

When compiling for Python 3.4 you can encounter the the missing
"ammintrin.h" header file error. Just copy it from the VS 2019
include/ directory.

For Pythons 3.5 / 3.6 / 3.7 / 3.8 / 3.9 you can use the same VC++ 14.2
(VS 2019) compiler which is binary compatible with VC++ 14.1 (VS 2017)
and VC++ 14.0 (VS 2015).

Currently the subprocess.exe executable built by Python 3.4 (VC++ 10.0
compiler) gives the least amount of false-positives by AVs on
virustotal.com . For comparison: Py34 (1/69), Py27 (2/69),
Py39 (5/69). Results differ for 32bit and 64bit binaries.

+## Seeking sponsors
+
+CEF Python is seeking companies to sponsor development of this project. Most important
+thing would be to have continuous monthly releases with updates to latest Chromium. There is
+also lots of cool features and new settings that would be nice to implement. We have not yet
+exposed all of upstream CEF APIs. If your company would like to sponsor CEF Python development efforts
+then please contact [Czarek](https://www.linkedin.com/in/czarektomczak/). There are no active sponsors
+at this moment.

-## Seeking new sponsors
-
-CEF Python is seeking companies to sponsor further development of the project.
-There are many proposals for new features submitted in the issue tracker. Most
-notable are:
-
-* Monthly releases with latest Chromium
-* An automated build system similar to upstream CEF Spotify Automated Builds
-* ARM and Android support
-* Multi-threaded support for increased performance
-* Proprietary codecs support in build tools: H264, H265,AC3, EAC3, MPEG-4
-* More CEF API exposed, only about 50% is exposed so far
-* Hundreds of new settings and Chromium preferences not yet exposed
-* Easier integration with popular GUI toolkits in just a few lines of code
-  and support for more third party GUI frameworks
-* More examples of implementing various advanced features and more snippets
-  as well
-
-If your company would like to sponsor CEF Python development efforts then
-please contact
-[Czarek](https://www.linkedin.com/in/czarektomczak/).
-Long term sponsorships are welcome and Czarek is open to ideas about
-the project. He would love to spend more time on developing this project,
-but he can't afford doing so in his free time. Currently there is no company
-supporting this project actively on a daily basis.
