24// There is a bug in 10.5 where you cannot stop an animation on a 
25// NSAnimatablePropertyContainer by just setting it's duration to 0.0.
26// The work around is rather complex requiring you to NULL out animation 
27// dictionary entries temporarily (see the code for details).
28// These categories are to make stopping animations simpler.
29// When you want to stop an animation, you just call it like you would
30// an animator.
31//
32// [[myWindow gtm_animatorStopper] setAlphaValue:0.0];
33//
34// This will stop any current animations that are going on, and will immediately
35// set the alpha value of the window to 0.
36// If there is no animation, it will still set the alpha value to 0.0 for you.
