[chromium] REGRESSION(r123644) Compositor HUD crashes immediately with --show-paint-rects
https://bugs.webkit.org/show_bug.cgi?id=92775
Reviewed by Adrienne Walker.
In r123644, the compositor HUD was turned into a normal layer. When the HUD is supposed to cover the entire
viewport - for instance if the showPlatformLayerTree or showDebugRects settings are true -
HeadsUpDisplayLayerChromium's constructor tries to size itself to its layerTreeHost()'s device viewport size.
Unfortunately, its layerTreeHost pointer is always nil in the constructor since the layer is not yet in the
tree. Additionally, this doesn't handle resize at all.
To fix this, this grabs the device viewport size and settings in a LayerChromium::update() OVERRIDE. Also
changes CCLayerTreeHost::willCommit to only reparent the HUD layer if needed instead of on every frame.
Tested manually, we don't have any layout tests for the debug HUD.
