- Move uniform declarations to the GLDEFS lump to make it Vulkan safe (a vulkan implementation can then declare them in an uniform block)
- Change SetUniform functions to be clearscope as they can be safely called from both play and ui - Add PlayerInfo argument to SetUniform functions to force the modder to take network play into account - Add enabled flag on custom postprocess shaders - Removed custom texture support until a more clean implementation is written
