Fixed <rdar://problem/7401617> Selection painting issue in hardware-
accelerated layers
which is another part of ​https://bugs.webkit.org/show_bug.cgi?id=23628
Fix selection painting to do container-relative repaints

Reviewed by Darin Adler.

Test: fast/repaint/block-selection-gap-in-composited-layer.html

  • rendering/RenderBlock.cpp:

(WebCore::RenderBlock::selectionGapRectsForRepaint): Compute and paint
gap rects in the coordinate space of the repaint container.

  • rendering/RenderLayerCompositor.cpp:

(WebCore::RenderLayerCompositor::recursiveRepaintLayerRect): Added a
FIXME.

  • rendering/RenderView.cpp:

(WebCore::RenderView::setSelection): Map block selection gap rects from
the repaint container’s coordinate space to the view’s coordinate space
before adding them to the cached selection bounds.
(WebCore::RenderView::clearSelection): Changed to use
repaintRectangleInViewAndCompositedLayers() so that the selection rect
is invalidated in composited layers as well.
