- read sampler bindings from the shader instead of tagging along a large amount of support data.
...
Works for most shaders, except SSAO.

- specify fragment output locations in the shader source.
...
OpenGL has been supporting this since version 3.3 and Vulkan requires it so it's the way to go.

- removed 'cooling' component of the shader since it technically wasn't really functional (guess we have to use a separate shader to do that)
...
- changed the math to use the 'mix' formula

- expanded hard limits for saturation to -15.0/15.0
...
- added menu option for saturation
- tried to get the new saturation shader to consume less GPU power by turning it off when it is 1.0

- added a vid_saturation control - works in postprocessing, only.

Quick fix: prevents negative values being passed to pow.

Changes to the contrast/brightness/gamma formula for both hardware and shader gamma correction. Mainly makes a correction with the shader version where contrast/brightness being negative values would clip them inappropriately.

Make sure we never pass a negative value to pow, and optimize gamma uniform

Added patch shader support to FShaderProgram
Added OpenGL 2 fallback support to render buffers
