[CSS Blending] Compositing requirements for blending are not computed correctly https://bugs.webkit.org/show_bug.cgi?id=130664 Patch by Ion Rosca <rosca@adobe.com> on 2014-04-02 Reviewed by Dean Jackson. Source/WebCore: Tests: css3/compositing/blend-mode-accelerated-with-multiple-stacking-contexts.html css3/compositing/blend-mode-with-accelerated-sibling.html Compositing requirements for blending: if a layer having blend mode other than normal is composited for any reason, its closest stacking context ancestor should be composited as well. * rendering/RenderLayer.cpp: (WebCore::RenderLayer::RenderLayer): * rendering/RenderLayer.h: added a new field, m_hasUnisolatedCompositedBlendingDescendants, which is true if the layer has composited blending descendants not isolated by any stacking context child; added a new method: isolatesCompositedBlending(), which is true if we should accelerate that layer in order to perform isolation correctly. * rendering/RenderLayerCompositor.cpp: (WebCore::CompositingState::CompositingState): m_subtreeHasBlending was renamed m_hasUnisolatedCompositedBlendingDescendants in order to be more self-explanatory. (WebCore::RenderLayerCompositor::computeCompositingRequirements): computes the isolation requirements for composited blending by (re)setting RenderLayer::m_hasUnisolatedCompositedBlendingDescendants flag. (WebCore::RenderLayerCompositor::reasonsForCompositing): fixed the reason of compositing: isolation instead of blending.

[CSS Blending] Cleanup tests in css3/blending https://bugs.webkit.org/show_bug.cgi?id=132600 Reviewed by Mihnea Ovidenie. Summary of changes: - move common stylesheet classes to blending-style.css. - remove trailing white spaces. - replace tabs with spaces. - remove the 'html' tags for consistency with the most of blending tests. This patch does not change the txt and png test expectations. * css3/blending/background-blend-mode-background-attachement-fixed-expected.html: *
