Constrain Within Circle?

Hi Joel,

It is. In my test using atan instead of atan2 was a few milliseconds 
faster. Not too many though. in 350 loops and 50 test runs the atan 
version was about 70 millisecs faster on a G4 - 400 MHz than the atan2 
version. That´s why I chose the longer form. But this is so close that 
there might be factors that give a faulty result (are there any other 
apps open using cycles etc...)

All the best,

Malte
