Add the ability for the GPU process to be used to paint the backing store of a
tab. This is the first pass and is currently a bit buggy and incomplete.
This patch refactors the backing store to make it a virtual interface which is
then implemented by the platform-specific backing stores. This cleans up the
multi-platform aspects of the old code, and also makes it possible to create
different backing stores (such as ones in another process).
This renames the BackingStore::PaintRect function to PaintToBackingStore which
clears up what it does. I would often get confused and think that it paints
the backing store to the screen.
This makes a common way to capture backing store information and adds it to the
backing store API. This removed a bunch of ugly ifdefs.
This adds the ability for a backing store to specify that the TransportDIB
should not be freed by RenderWidgetHost when painting is complete. This is
necessary since the out-of-process version needs to use it after the
RenderWidget paint function has returned.
This pushes up the vector of copy_rect from RenderWidgetHost to the actual
BackingStores. This prevents us from sending duplicate data over IPC. It also
makes the common non-IPC case more efficient, since we end up setting up various
surfaces only once when there are multiple update rects.
