RenderLayerCompositor should let ScrollingCoordinator update main thread scrolling reasons after change of layers https://bugs.webkit.org/show_bug.cgi?id=105652 Reviewed by Simon Fraser. Source/WebCore: Let ScrollingCoordinator know the change of ViewportConstrainedNotCompositedReason in time. By the way moved RenderLayerCompositor::FixedPositionLayerNotCompositedReason to RenderLayer::ViewportConstrainedNotCompositedReason. Tests: compositing/layer-creation/fixed-position-in-view-dynamic.html compositing/layer-creation/fixed-position-out-of-view-dynamic.html * page/scrolling/ScrollingCoordinator.cpp: (WebCore::ScrollingCoordinator::hasVisibleSlowRepaintViewportConstrainedObjects): (WebCore::ScrollingCoordinator::mainThreadScrollingReasons): (WebCore::ScrollingCoordinator::mainThreadScrollingReasonsAsText): * page/scrolling/ScrollingCoordinator.h: (ScrollingCoordinator): * page/scrolling/mac/ScrollingCoordinatorMac.h: (WebCore::ScrollingCoordinatorMac::hasVisibleSlowRepaintViewportConstrainedObjects): * page/scrolling/mac/ScrollingTreeScrollingNodeMac.mm: (WebCore::logThreadedScrollingMode): * rendering/RenderLayer.cpp: (WebCore::RenderLayer::RenderLayer): (WebCore::RenderLayer::paintLayer): * rendering/RenderLayer.h: (RenderLayer): Moved RenderLayerCompositor::FixedPositionLayerNotCompositedReason to here and renamed it to ViewportConstrainedNotCompositedReason. (WebCore::RenderLayer::setViewportConstrainedNotCompositedReason): (WebCore::RenderLayer::viewportConstrainedNotCompositedReason): * rendering/RenderLayerCompositor.cpp: (WebCore::RenderLayerCompositor::updateCompositingLayers): (WebCore::RenderLayerCompositor::updateBacking): Now updates ViewportConstrainedNotCompositedReason here instead of in computeCompositingRequirements before so that the reason is updated in time.
