[from {BLT}, q.v.:]
1. [common] 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).
2. Synonym for {blit} or {BLT}. Both uses are borderline techspeak.
