This implementation supports both GPU compositing and software compositing (used when GPU is not supported or when passing `--disable-gpu --disable-gpu-compositing` command-line flags). GPU-accelerated features (WebGL and 3D CSS) that did not work with the previous off-screen rendering implementation do work with this implementation when GPU support is available.
Rendering now operates on a per-frame basis. The frame rate is configurable via CefBrowserSettings.windowless_frame_rate up to a maximum of 60fps (potentially limited by how fast the system can generate new frames). CEF generates a bitmap from the compositor backing and passes it to CefRenderHandler::OnPaint.
The previous CefRenderHandler/CefBrowserHost API for off-screen rendering has been restored mostly as-is with some minor changes:
- CefBrowserHost::Invalidate no longer accepts a CefRect region argument. Instead of invalidating a specific region it now triggers generation of a new frame.
- The |dirtyRects| argument to CefRenderHandler::OnPaint will now always be a single CefRect representing the whole view (frame) size. Previously, invalidated regions were listed separately.
- Linux: CefBrowserHost::SendKeyEvent now expects X11 event information instead of GTK event information. See cefclient for an example of converting GTK events to the necessary format.
- Sizes passed to the CefRenderHandler OnPaint and OnPopupSize methods are now already DPI scaled. Previously, the client had to perform DPI scaling.
- Includes drag&drop implementation from issue #1032.
- Includes unit test fixes from issue #1245.

- Popup menus, drag&drop and GPU acceleration are not currently supported.
- Testing is enabled in cefclient by passing the "off-screen-rendering-enabled" command-line flag.

- Change index parameter types from int to size_t to make 0-based range implicit.
- Make CefPrintOptions and CefMenuInfo proper wrapper classes.
- Normalize the naming of menu-related types.
- Remove unused command_line variable from test_suite.cc.

- Replace CefHandler with a new CefClient interface and separate handler interfaces.
- Add support for virtual inheritance to allow multiple CefBase parented interfaces to be implemented in the same class.
- Replace CefThreadSafeBase with IMPLEMENT_* macros to support virtual inheritance and to only provide locking implementations when needed.
- Move the CefBrowserSettings parameter from CefInitialize to CreateBrowser.
- Add a new cef_build.h header that provides platform-specific and OS_* defines.
- Introduce the use of OVERRIDE to generate compiler errors on Windows if a child virtual method declaration doesn't match the parent declaration.
- Use NDEBUG instead of _DEBUG because _DEBUG is not defined on Mac. (issue #240).
