- Fix OpenGL software diminishing light to be identical to truecolor swrenderer and softpoly
...
All there is left is to make globVis an uniform and move the LightVisibility::SetVisibility calculations out of the software renderer.
That will make it 100% correct for all r_visiblity values and aspect ratios.

* disable the dynamic light code if no buffers are available
* added a duplicate of the getTexel function which cannot be patched without creating syntax problems.
* fixe int<->float conversion warning, which on some compilers may be an error.

- fixed: Even though the name REDISALPHA implies otherwise, this render mode still needs to respect a texture's alpha channel to ensure that things get rendered properly. Otherwise the SmoothEdges function cannot be used which is necessary to ensure that filtered textures look correct.

- fixed: When changing enhanced nightvision mode the shaders need to have their fixed colormap state reset to ensure that the new settings get used.

- removed the 'layout' qualifier from the uniform buffer declaration. It's not really needed because the layout of a single vec4 array cannot possibly change, and Intel drivers are complaining for unknown reasons.

- changed the handling of alpha textures. The only special case they need is with palette-less textures and this can be handled far more easily and robustly with a predefined translation instead of passing another parameter through all the layers of the texture management code. This also fixes problems with paletted PNGs that get used as an alpha texture because the old method clobbered the image's palette.

- reactivate alpha testing per fixed function pipeline
- use the 'modern' way to define clip planes (GL_CLIP_DISTANCE). This is far more portable than the old glClipPlane method and a lot more robust than checking this in the fragment shader.

Do not use the shader to handle STYLEF_RedIsAlpha.
...
Turns out that the name doesn't accurately describe what it does.
It is correct for images that come with their own palette or are true color.
But for images using the game palette it doesn't use the red channel to determine translucency but the palette index! Ugh...
This means it cannot be done with a simple operation in the shader because it won't get a proper source image. The only solution is to create a separate texture.

Further cleanup of lighting code.
...
- remove thing color from lighting calculations.
- implement alpha textures and inverse sprites for infrared as texture modes. This still requires some handling for the alpha texture mode for non-shader rendering because there is no way in the fixed pipeline to do it. The inverted texture effect can be done with a texture combiner.
- fixed: ThingColor for sprites was set in the wrong place. It must be in the Process function, not in the lighting calculation.
- added functions for isolated calculation of sprites' dynlight color.
