-        [chromium] REGRESSION(r120346) ContentLayerPainter should clear rect to be painted
-        https://bugs.webkit.org/show_bug.cgi?id=89376
-
-        Reviewed by Adrienne Walker.
-
-        In r120346, a refactor moved a clearRect()/clip() call from ContentLayerPainter - which all
-        ContentLayerChromiums use - out to OpaqueRectTrackingContentLayerDelegate - which all GraphicsLayerChromium
-        backed layers use, but which callers using WebContentLayer directly do not use. This meant that the canvas
-        wasn't cleared/clipped as WebContentLayerClient.h claimed it would be. This moves the clear and the clip
-        into CanvasLayerTextureUpdater which all paths use, including layers that don't use the ContentLayerPainter.

+        [Chromium] Compositor should avoid drawing quads when cached textures are available and contents unchanged

+        Post-processing CCRenderPassList after it's been generated and
+        removing all render surface quads for which there are
+        cached textures, and whose content didn't change. Added a new
+        flag to CCLayerImpl to differentiate surface property change and
+        layer property change.
+
+        The changes are covered by new unit tests that check that
+        the removal algorithm functions propertly. No rendering
+        behaviour change, so no new layout tests.
