-	clip the source rectangle to the source's available bits.  (this
-avoids copying unnecessary pieces that will just get exposed anyway.)
-this becomes the new shape of the destination.
-	clip the destination region to the composite clip in the
-GC.  this requires translating the destination region to (dstx, dsty).
-	build a list of source points, one for each rectangle in the
-destination.  this is a simple translation.
-	go do the multiple rectangle copies
-	do graphics exposures
-*/
-/** Optimized for drawing pixmaps into windows, especially when drawing into
- ** unobscured windows.  Calls to the general-purpose region code were
- ** replaced with rectangle-to-rectangle clipping comparisions.  This is
- ** possible, since the pixmap is a single rectangle.  In an unobscured
- ** window, the destination clip is also a single rectangle, and region
- ** code can be avoided entirely.  This is a big savings, since the region
- ** code uses XAlloc() and makes many function calls.
- **
- ** In addition, if source is a pixmap, there is no need to call the
- ** expensive miHandleExposures() routine.  Instead, we simply return NULL.
- **
- ** Previously, drawing a pixmap into an unobscured window executed at least
- ** 8 XAlloc()'s, 30 function calls, and hundreds of lines of code.
- **
- ** Now, the same operation requires no XAlloc()'s, no region function calls,
- ** and much less overhead.  Nice for drawing lots of small pixmaps.
