cc: Minimize the number of times GL scissoring state is changed

We may sometimes want to turn off the scissoring optimization. At this time
scissoring is used as both an optimization and for correctness when a layer is
clipped. This patch separates those concepts and rearranges scissoring logic
in an attempt to minimize how often scissoring state changes; scissoring
changes very likely cause graphics pipeline to flush which is definitely
undesirable.
