LayoutTests/virtual/softwarecompositing/squashing/squashed-repaints-expected.txt

 Basic repaint test for squashed layers. The entire squashing layer should not need repainting when only a portion of it is invalidated. Test interactively by using --show-paint-rects and hovering over elements to change their color.
