Custom PPSSPP shaders

[LunaMoo]

Have fun with those, if you ever will need to animate something, remember we also have u_time uniform - here's Henrik post explaining all of it's arguments.
You can make big as well as very subtle changes pretty easily with those, althrough better not to abuse this too much, quick and distracting changes in image make lots of people sick, I can't even look at CRT post proc shader included with ppsspp without my eyes trying to follow the movement of lines~_~.
