Lot's of people have been complaining about the use of copy protection. I
won't get into that now, but I do have a comment about the claims that it
isn't necessary to reach deep into the software to get adequate animation.

Have you tried it? If not, please don't make uneducated comments - they are
of little value. I've played around with an 'asteroids' program which runs
in an Intuition window. 10 asteroids is jerky. 25 is a mess. All of the
asteroids are blitter objects. (I tried VSprites, but they didn't work - they
are also not clipped.) My screen was low res, using only 1 bit per pixel.

If I work some more on the program, I'll re-arrange it to not use windows,
and clip the VSprites manually as they go over the screen's title bar (which
can't be removed without using a backdrop window). (There has to be SOMETHING
on the screen other than the asteroids, etc.!!) Also note that it does not
appear to be possible to make the pointer go away when using Intuition. You
CAN redefine it away however, but you are permanently out 1 sprite out of
8 and 1 out of 4 sprite color sets.

To the guru's out there: is there a GelsInfo around somewhere that I'm
supposed to use? Calling InitGels myself and stuffing the pointer into
Intuition's window/screen seems a bit brutal. (I'm not sure if I've played
with it at all under V1.1, certainly haven't tried the new C compiler.)
