bitblt

/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).

2. blit, BLT.
