rz5	a0608ed481	Update aann.slang ... Notable changes: * As per https://www.opengl.org/wiki/GLSL_Optimizations, I tried replacing divisions with multiplications. * All the color space conversion functions accept (and work on) vectors instead of single. This part is subjective, but I formatted the code all around based on my idea of what looks most legible . @wareya, @Monroe88: Hi, could you both take a quick glance at my multiply-add optimizations? The wiki says it would make it faster, dunno by how much but it was easy to change and it didn't hinder legibility too much.	2016-07-19 14:20:30 +01:00
