Record possible clip rejects when recording display lists
This optimization allows us to quickly skip operations that lie
entirely outside of the known bounds of a display list. Because
of ViewGroup.setClipChildren, we must keep the operations recorded
in the display list. setClipChildren(false) is however a very
uncommon operation and we will therefore often benefit from this
new optimization.
