     /bit'blit/ [BLT] 1. Any of a family of closely related
     algorithms for moving and copying rectangles of bits between
     main and display memory on a bit-mapped device, or between
     two areas of either main or display memory (the requirement to
     do the Right Thing in the case of overlapping source and
     destination rectangles is what makes BitBlt tricky).
