Blit a multi-rectangular area within a region
int PhMultiBlit( PhRid_t rid, unsigned short nrects, const PhRect_t rects, const PhPoint_t *offset );
This function “blits” the multi-rectangular area that is defined by the PhRect_t structures pointed to by rects and whose origin is defined by the origin of the region specified by the PhPoint_t structure pointed to by rid. The area is blitted by the given offset. Other windows aren't affected by the blit.
