Constrain Within Circle?

[Malte Brill]

Hi Joel,

Maybe it was my limited number of loops that didn´t produce a 
meaningful result. :-) Anyway, your version is so much more readable, 
and in single calls they are head to head anyway, that I will likely 
change the function in the next version of AE. Thanks very much for the 
suggestion.

All the best,

Malte
