+
+ Reviewed by Tim Horton.
+
+ When displaying RemoteLayerBackingStore, we copy the back buffer to the front
+ buffer before painting the updated regions. For buffers using Format::RGB10A8,
+ the CGImage-based copy fails, so in this case, use IOSurface::copyToSurface().
+
+ Reorganized RemoteLayerBackingStore::drawInContext() to make this a bit easier
+ to understand. First, we either copy the entire surface over, or paint the backImage.
+ Then we clip to the dirty rects, and clear them, then paint the layer contents.
