Synonym for {blit}. This is the original form of {blit} and the
ancestor of {bitblt}. It referred to any large bit-field copy or move
operation (one resource-intensive memory-shuffling operation done on
pre-paged versions of ITS, WAITS, and TOPS-10 was sardonically
referred to as "The Big BLT"). The jargon usage has outlasted the
{PDP-10} BLock Transfer instruction from which {BLT} derives;
nowadays, the assembler mnemonic {BLT} almost always means "Branch if
Less Than zero".
