SetImage renamed to SetFromImageData
Spining blur shader shader
A few hacks to experiment with depth mask to normal conversion and how it would look like as a game arena... so far so good :)
An improved and faster normal map generator, a new arena and changed bits of the behaviour of the top
Corrected the function, the order was wrong and we also need to preserve B1 for the next round where it becomes B0
Final optimisations and bilinear interpolation for the top.
