vmware/saa: Fix saa_check_copy_window dirty region v3
The saa_check_copy_window could dirty regions that were never touched, since
we were using the X server provided damage region rather than the more
detailed region actually copied. This would have been OK if we had first done
a read-back of the region to be dirtied, but since we want to avoid that,
instead compute the detailed destination region and use that for dirtying.
This fixes rendering glitches seen with motif applications.
v2: Fix whitespace error.
v3: Move dirty region computation.
