When using clip-rectangles and a non-identity transformation on a mask, the clip-rectangles are ignored.

Updated test case.

Just tweaked the test case to use the XRenderFormat associated with the DefaultVisual instead of assuming it is RGB24 and similarly to use the depth of the format, etc.

I get the same [clipped] results on all drivers, not too unsurprising as this should be handled by miComputeCompositeRegion(). So AFAICT this bug is fixed.
