This was done to make reviewing easier, again because it is virtually impossible to search for the operators in the code.
Going through this revealed quite a few places where texture animations were on but shouldn't and even more places that did not check PASLVERS, although they were preparing some paletted rendering.
This is for Vulkan preparation where all of this needs to run in a user-specified context so that this code can be moved out of the GL folder without depending on OpenGL's global state model.
These files are not part of the actual renderer but part of the system code.
This means, for separated modern and legacy GL renderers, there still will only be one set of this, unlike everything else.
This was done mainly to reduce the amount of occurences of the word FTexture but it immediately helped detect two small and mostly harmless bugs that were found due to the stricter type checks.
- 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
