- 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. git-svn-id: https://chromiumembedded.googlecode.com/svn/trunk@979 5089003a-bbd8-11dd-ad1f-f1f9622dbc98
