bitblt
 /bit'blit/, n.

   [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.
