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	b61ef3a107	- bumped minimum supported OpenGL version to 1.4. The engine was already using several 1.3 and 1.4 features which would have caused problems on 1.2. ... - removed gl_vid_compatibility. With the bump to 1.4 no hardware requiring this flag is supported anymore. - disabled 16 bit framebuffers for the same reason. As a conseqence all code for rendering without stencil could also be removed.	2013-08-18 15:41:52 +02:00
