   You know... That's what I've always though.
   Why file down a spoon into a fork, just to eat soup?
   It requires changing a lot of other ways of looking at
   things, though, and if you are using compass points, then
   it gets really messy unless you use 512 and approximate.
   For rotating a display, however, where all you need is a full
   circle of mobility and not exact degrees, then 255 would
   seem to make sense. I've never attempted to do anything with
   that idea, however, and probably won't.
   I can run down to the local Best Buy store and get VC++ 4.0
   Standard with a fully developed 3D/2D graphics lib and also
   a sound lib for around $50, so I don't suppose I even have
   any incentive.
