-----------
Apply the dirty rectangle to the ClipRects of LayerFragment only when they
are requested
https://bugs.webkit.org/show_bug.cgi?id=298845
rdar://160585141
Reviewed by Simon Fraser.
LayerFragment::Rects will be added to hold the return of
RenderLayer::calculateRects().
dirtyBackgroundRect() and dirtyForegroundRect() will return the intersection of
their rectangles and the dirty rectangle. This will allow returning the un-dirty
rectangles if needed.
Also there is no need to calculate all the ClipRects and BoundingBoxes when only
one rectangle is required. Refactoring LayerFragment::Rects should make this
doable
and cleaner.
