Bug 1373739 - Make headless compositing Windows-compatible, in addition to Linux. r=dvander To make the HeadlessCompositorWidget work under Windows as well as Linux, I had to change the way that I hooked it into the existing CompositorWidget system. Under GTK, the CompositorWidgetInitData and CompositorWidgetDelegate types provided the information needed by the headless compositor widget already (the widget client size). On Windows, however, the definitions of these types differ, and the client size information is simply retrieved from the platform APIs when needed. After this patch, CompositorWidgetDelegate is renamed to PlatformCompositorWidgetDelegate, and a new base class called CompositorWidgetDelegate is added with "AsPlatformSpecificDelegate()" and "AsHeadlessCompositorWidget()" methods. In non-headless mode, widgets use AsPlatformSpecificDelegate() to access the Windows- and GTK-specific delegate APIs. In headless mode, AsHeadlessCompositorWidget() is used to access the singular CompositorWidget implementation for headless. Meanwhile, the CompositorWidgetInitData IPDL type is made into a union which always contains a headless-specific HeadlessCompositorWidgetInitData struct and under GTK and Windows also contains an {X11,Win}CompositorWidgetInitData struct. This also includes a small patch to ensure that the GPU process and hardware-accelerated compositing are always disabled under headless mode. These features weren't activated by default in the Linux environments I tested in, but did end up activating (and then promptly crashing Firefox) when I tested on Windows.

Bug 1453629 - nsIWidget::GetNativeIMEContext() should return pseudo IME context if TextInputProcessor has a composition on the widget r=m_kato Key of TextCompositionArrary to search composition on widget is native IME context. However, if TextInputProcessor dispatches composition events via TextEventDispatcher, TextEventDispatcher::InitEvent() sets native IME context of dispatching composition events to pseudo IME context (that's raw pointer of TextEventDispatcher and process ID). IMEStateManager::DispatchCompositionEvent() looks for existing TextComposition with native IME context stored in WidgetCompositionEvent before dispatching an event. However, after dispatching it, it looks for remaining TextComposition instance with widget stored in WidgetCompositionEvent. Then, TextCompositionArrary::IndexOf(nsIWidget*) will look for an instance with the result of nsIWidget::GetNativeIMEContext() and this never returns actual native IME context. Therefore, IMEStateManager::DispatchCompositionEvent() always fails to remove TextComposition instance from the array even after a test composition is finished. This patch moves nsIWidget::GetNativeIMEContext() to nsBaseWidget to refer nsBaseWidget::mTextEventDispatcher makes it return pseudo IME context if TextInputProcessor has input transaction. Therefore, IMEStateManager becomes always removes TextComposition from the array when every composition ends.
