Like many systems, the Amiga has many levels of possible access, from ROM
code which will do all the blitter stuff for you, to library calls which
allow you to more directly control the blitter itself, to getting down and
banging on the blitter's register bits by hand.  Which technique you use
depends on what you're trying to do, and the speed you want to do it at.
