:blit: /blit/ vt. 1. To copy a large array of bits from one part
of a computer's memory to another part, particularly when the
memory is being used to determine what is shown on a display
screen. "The storage allocator picks through the table and copies
the good parts up into high memory, and then blits it all back down
again." See {bitblt}, {BLT}, {dd}, {cat}, {blast},
{snarf}. More generally, to perform some operation (such as
toggling) on a large array of bits while moving them. 2. Sometimes
all-capitalized as `BLIT': an early experimental bit-mapped
terminal designed by Rob Pike at Bell Labs, later commercialized as
the AT&T 5620. (The folk etymology from `Bell Labs Intelligent
Terminal' is incorrect. Its creators liked to claim that "Blit"
stood for the Bacon, Lettuce, and Interactive Tomato.)
