Richard,  "bitblt" is a pseudonym for "bit-mapped block transfer", and from
my understanding of it, it is a hardware device capable of moving data that
is defined on bit boundaries from one location in memory to another.  It is
used extensively in raster graphics hardware, to optimize line and area
operations.   Unfortunately, that's about all I know on this subject.
