Bug 236638

Currently we call ImageBuffer::drawPattern() directly. This does not record the drawing when GPU Process rendering is enabled. We need to route this call through GraphicsContext so it can be record via the superclasses DisplayList::RecorderImpl and RemoteDisplayListRecorderProxy. We currently hit the following assertion when enabling the GPU Process rendering for DOM: SHOULD NEVER BE REACHED
