Christoph Oelckers	887d35d559	- remove colormap from texture generation parameters. The one remaining special case, alpha texture on old hardware is now handled by the currently set texture mode at the time of use. ... - use the cleaned up decal lighting code from the first GLEW branch.	2014-05-11 19:44:19 +02:00
Christoph Oelckers	7793bbbcc9	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.	2014-05-11 17:56:38 +02:00
