Another slight update to MGViewAnimation (available on the Cocoa Source Code page). This one just adds an override of the -stopAnimation method to behave like NSViewAnimation’s does (i.e. move all animations to their end frame), and a slight optimization. I also got around to including the license in the actual download.
Same license as before, and this should be a drop-in replacement requiring no changes to any of your existing code which uses the class. Quite unexciting, really.
