Description Said Abou-Hallawa 2020-11-11 21:26:00 PST 
This is very similar to the DisplayList::DrawImageBuffer item. All we need is to record the renderingResourceIdentifier of the ImageBuffer. At replaying time, the renderingResourceIdentifier of the ClipToImageBuffer will be resolved to an ImageBuffer. The actual clipping will be moved to an new function named ImageBuffer::clipToMask().
