GPU Easing

Robert Penner's easing equations have been around for a number of years and are widely used. However I've never seen them being used on the GPU in a vertex shader, so I decided to give it a try. In this experiment you can choose between a couple of meshes and even get 'extra crazy' if you like. Oddly enough the weirdness you see when going extra crazy started life as a bug in my code, but it was so cool that once I fixed it I introduced it again, but this time done intentionally.
