This function performs operations on a region, and when finished, checks to see if it should compact the rectangle list. If the number of rectangles for which memory is allocated in the list is more than twice the number used, it tries to shrink. realloc() should not fail in this case, but if it does, might as well keep the correct value for the number of allocated rectangles, so we don't try to grow it unnecessarily later if adding to the region.
