[jitter] [Sharing is Fun] - GPU powered frame blending (working now... !)

Hi.

Here is an updated frame blending patch for jit.qt.movie which  
interpolates between frames when y... o.... u... a... r... e... g...  
o... i..... n........ g...... s......... l.......... o.........

It has a weird issue where you MAY have to re-instantiate  
jit.gl.render. Not sure why. This version now works in reverse, and is  
smart enough to get out of the way if you set your rate above 0.9, so  
you dont have the extra overhead of running the movie through a mixer  
for no reason. Note I use my lumablend shader, which I think looks  
better, but feel free to throw in what you want. Its also pretty close  
to an abstraction already, so you can drop it in to existing stuff  
without too much trouble.
