Move all fast-path paint invalidation mapping into PaintInvalidationState
- Remove the optional const PaintInvalidationState* parameter from paint
invalidation mapping methods and move fast-path mapping code into
PaintInvalidationState.
- PaintLayer::computePaintInvalidationRect() is now
PaintInvalidationState::computePaintInvalidationRectInBacking();
PaintLayer::positionFromPaintInvalidationBacking() is now
PaintInvalidationState::positionFromPaintInvalidationBacking();
PaintLayer::mapRectToPaintInvalidationBacking() is now
PaintInvalidationState::mapLocalRectToPaintInvalidationBacking().
- Change LayoutObject::clippedOverflowRectForPaintInvalidationBacking() to:
* Non-SVG objects and LayoutSVGRoot:
LayoutObject::localOverflowRectForPaintInvalidation() which doesn't
map the rect to paint invalidation backing;
* SVG objects except LayoutSVGRoot:
Using existing paintInvalidationRectInLocalSVGCoordinates()
PaintInvalidationState::computePaintInvalidationRectInBacking(),
calls the above functions to get the local paint invalidation rect,
and map to paintInvalidationContainer using fast path if possible,
or slow path by calling LayoutObject::mapToVisibleRectToAncestor().
- Let selection paint invalidation go through fast-path if possible.
