[Chromium] Occlusion tracking with CSS filters https://bugs.webkit.org/show_bug.cgi?id=77498 Patch by Dana Jansens <danakj@chromium.org> on 2012-02-16 Reviewed by James Robinson. Source/WebCore: The new CSS filter support within the compositor changes how occlusion tracking needs to function. A filter can change the alpha value of pixels, making an otherwise opaque pixel no longer so. Secondly, a filter may move color values around on a surface, which can cause otherwise occluded areas to become visible and require painting.
