            Bug ID: 236638
           Summary: [GPU Process] Make GraphicsContext::drawPattern() work
                    for ImageBuffer as an argument
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering

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
