[Pixman] [PATCH 2/2] _intersect_rect should return an empty region when intersecting with an empty rect

When you call _intersect_rect and pass it an empty rectangle, it creates an invalid region from that rectangle. The only valid empty region is the one where the data pointer points to pixman_region_empty_data. The region created by _intersect_rect has a null data pointer, and so _not_empty returns
