The blitter takes care of almost all of the Amiga's
bitmapped graphics manipulation, from drawing lines
to moving objects and filling outlined areas.
Intuition, for example, uses the blitter for such
things as drawing gadgets and printing text. And
one of the best things about the blitter is that it
executes independently, allowing the Amiga to
animate objects while the CPU is hard at work
executing program instructions.
