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.

- The sandbox is now enabled by default on all platforms. Use the CefSettings.no_sandbox option or the "no-sandbox" command-line flag to disable sandbox support.
- Windows: See cef_sandbox_win.h for requirements to enable sandbox support.
- Windows: If Visual Studio isn't installed in the standard location set the CEF_VCVARS environment variable before running make_distrib.py or automate.py (see msvs_env.bat).
- Linux: For binary distributions a new chrome-sandbox executable with SUID permissions must be placed next to the CEF executable. See https://code.google.com/p/chromium/wiki/LinuxSUIDSandboxDevelopment for details on setting up the development environment when building CEF from source code.

- Pass popup window attributes to CefLifeSpanHandler::OnBeforePopup (issue #520).
- Windows: Add manifest files for all binary targets and include compatibility manifest in *.exe targets.

- Build with the 10.7 SDK (set GYP_DEFINES='mac_sdk=10.7') to include Retina support in the cefclient OSR example.

- Implement support for transparency. Change the backing store to use Skia instead of GDI and to keep alpha values.
- Implement support for select popups. Requires a patch to Chromium (content_popups.patch).
- Implicitly disable accelerated compositing when using off-screen rendering.
- Introduce a new CefMouseEvent structure for representing mouse event information passed to CefBrowser methods.
- Merge cef_key_event_modifiers_t into cef_event_flags_t.
- Add a new argument to CefBrowser::Invalidate telling the browser whether to invalidate the select popup or the main view.
- Add a new cefclient "transparent-painting-enabled" command-line flag to test transparent off-screen rendering.
- Add a new cefclient "Transparency" test.
- Fix the cefclient off-screen rendering rotation effect to work even when the underlying web content is not updating.
- Add unit tests for transparent painting and select popups.

- 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.

- Add about:tracing UI support (issue #711).
- Avoid unnecessary string type conversions for values and process messages.
- Add support for a 'note' attribute in patch.cfg.
git-svn-id: https://chromiumembedded.googlecode.com/svn/trunk@865 5089003a-bbd8-11dd-ad1f-f1f9622dbc98
- Add a new CefBrowserHost::RunFileDialog method that displays the specified file chooser dialog and returns the results asynchronously (issue #761).
- Add a new CefDialogHandler::OnFileDialog callback that allows the application to provide custom UI for file chooser dialogs (issue #761).

- Move custom scheme registration to CefApp::OnRegisterCustomSchemes(). This is required by the introduction of ContentClient::AddAdditionalSchemes() and fixes a race condition when registering standard schemes in different processes.
- Execute V8 functions using V8Proxy. This is required for inspector instrumentation to work correctly and fixes an assertion in WebCore related to V8RecursionScope.
- Enable verbose V8 TryCatch logging.
- Mac: Expose UnderlayOpenGLHostingWindow interface that should be used for all CEF windows.
- Add CefSettings.remote_debugging_port option.

- Add CefJSDialogHandler and CefJSDialogCallback interfaces.
- Add default dialog implementations for Windows and Mac OS-X.
- Add "JavaScript Dialogs" example to cefclient.
- Change TestHandler::AddResource to ignore the query component when matching URLs.

- Move wrapper classes from cef_wrapper.h to wrapper/ directory.
- Move C API functions/classes from cef_capi.h to capi/ directory.
