+ What's uVelocityScale? It's used to address the following problem: 
+ if the framerate is very high, velocity will be very small as the 
+ amount of motion in between frames will be low. Correspondingly, if 
+ the framerate is very low the motion between frames will be high 
+ and velocity will be much larger. This ties the blur size to the 
+ framerate, which is technically correct if you equate framrate with 
+ shutter speed, however is undesirable for realtime rendering where 
+ the framerate can vary. To fix it we need to cancel out the framerate
