Christoph Oelckers	b9a6fe80a4	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.	2014-05-11 23:56:53 +02:00
Christoph Oelckers	978ace241c	- removed all code that mixes together the different lighting methods. Now everything goes through the 3 different light parameters in the render state. ... - removed cm parameter from many functions.	2014-05-11 21:47:54 +02:00
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
