PutImage/PutStill respect the GC clip, however ReputImage does not.
PutImage/PutStill are supposed to be oneshot operations so ReputImage
should never expand the area covered by the clip, instead it should
only shrink if the window clip shrinks. So commandeer clientClip
into use by ReputImage and initially make it a copy of the original
GC composite clip. Whenever ReputImage needs reclipping update
clientClip with the newly calculated composite clip.
