using noels test above
- with 100 5 point poly objects - i get 26 fps
on this 800mhz duron - at 60 objects its still above 60fps
on this system.

- noel gets approx 60fps -
- on AMD64 3000+

100 balls = 9,900 checks per frame

seems pretty decent...

i changed the code to use imagescollide() & clearcollisions()
- with only 15 objects, the fps dropped below 60..this
- is approx 1/4 the performance. hmmm probably cuz
- my processor sucks the big one..
