---- Reported by andrewdavison62 2006-02-19 19:47:12 ----

The JOGL utility class FPSAnimator uses java.util.Timer.schedule() to trigger 
redraws of drawables. schedule() suffers from drift so that it's fairly useless 
for triggering accurate updates for frame rates above 50 FPS.

Please add a flag to FPSAnimator's constructor to allow the optional use of 
java.util.Timer.scheduleAtFixedRate(), which performs better at higher FPSs.

The code changes would occur in FPSAnimator's start() method.

Added new constructors taking fixed-rate scheduling flag. Defaults to false.
Seems to help FPSAnimator reach higher framerate targets. Unclear whether the
flag will cause excessive CPU consumption.
