- Restore CefRenderHandler::OnScrollOffsetChanged. - Add new RT_PING and RT_SERVICE_WORKER resource type values. - The resource type for image sub-resource loads has changed from RT_IMAGE to RT_PREFETCH (this is a regression, see http://crbug.com/415253#c23). - Add a patch to fix a crash in Scheduler::swapQueuesRunPendingTasks* (http://crbug.com/415478). - Add documentation for cef_key_event_type_t values. git-svn-id: https://chromiumembedded.googlecode.com/svn/trunk@1846 5089003a-bbd8-11dd-ad1f-f1f9622dbc98
