Build 080721 - Revision 5

Struggling with the new collision system (basically because I don't want to make those collision meshes manually anymore, which is essential for the multi-level build) I found the last of the RNG glitches, causing the banding effect with the radial blur on some drivers... No idea what causes it, but it worked nicely on GTX1080, yet caused a lot of banding on 1660TI. It is gone now (it was never supposed to be there in first place, as unlike with many other implementations, the radial blur here can cause noise, but never any banding)... Anyway:

• A really tiny fix removing the banding artifacts when using the radial blur effect on some GPU/driver combinations.
