cc: Fix clipped render surface caching.
Fix this by considering clipping from outside of the target surface as
occlusion from outside the target surface. We clip quads by the various
rects including the device viewport. When we do this, it should count as
occlusion from outside of the target surface so that surfaces do not
consider themselves complete when they are not fully drawn because they
extend outside the viewport.
The OcclusionTrackerTestLayerClipIsExternalOcclusion test will pass
without this CL as clipping does not cross surface boundaries in the
occlusion tracker right now, except for the screen space (viewport) clip
rect. I've added some TODOs where we could change this behaviour and
clip more aggressively things that will not be seen.
Tests:
