Custom PPSSPP shaders

[LunaMoo]

You don't need to mix effects together for PPSSPP anymore, PPSSPP supports multi pass shaders and you can freely mix effects as you wish and do it directly from UI.
PPSSPP UI even includes shader parameters/settings as long as the author of the shader included some. Post process effects were moved not long ago to Display Layout & Effects screen where you can freely select and mix many effects together.
