<rdar://problem/15769454>

Various things can cause WebCore to override TiledCoreAnimationDrawingArea's transient zoom properties on the RenderView's layer.

Instead of letting that happen (which causes horrible jumping), if a layer flush ends up getting scheduled while we're zooming, we'll re-apply our properties after flushing layer changes.
