Just a digression on sprites - it seems a strange term to use. Some machines
such as the Commodore 64 had hardware-supported sprites: that is, the
graphics subsystem had registers that you could set to point to a little
sprite pixel map in memory, and set up the direction and velocity, and the
hardware would animate the little buggers at interrupt time. They were fun
to play with. I don't remember too many of the details, but it was an
interesting exercise to set up sprites using memory-mapped video and lots
of POKE commands from Commodore BASIC. I've never seen the term sprite used
to refer to code for Macs - is this common?
