[chromium] Animating opacity is not opaque and should create a render surface on main thread
Created attachment 132373 [details] Patch
This is probably not needed? a) If we don't have/don't have a render surface on main thread but opposite on impl, it shouldn't hurt anything. We don't commit the surface anyway. b) We don't depend on a surface on main thread for this anywhere.
Oh this does affect paint culling. If we make it own a render surface, then we can do scoped paint culling within the surface.
