CoreAnimation: Give app windows layers
On 10.6-10.8, there is a brief flicker of corruption when the
RWHVCocoa (which has a CALayer) is added to the already-visible
window's NSView hierarchy. I suspect that this is a mini-seizure
that the window system has when transitioning the window from
a "does not have layers" mode to a "has layers" mode. Adding a
layer to the window's NSView hierarchy before the window is made
visible makes this seizure not happen.
