Description Dave Hyatt 2017-08-09 12:19:45 PDT
Move layer repaint rects into a map. Since many layers aren't self-painting, they're wasting space holding those rects. In addition, once we start caching rects for RenderLayerModelObjects that don't have layers (i.e., everyone using a LayoutRepainter right now), then we'll want to have a common structure.
