Use an in process buffer when snapshotting for a frame containing a pdf. For
subframe pdfs, create a WebCore::Image using the underlying data of the
ShareableBitmap (which creates a CGImage using ShareableBitmap data as the
CGDataProviderRef) and draw that into the GraphicsContext displaylist,
which gets the image to the GPU process.
