Christoph Oelckers	f3a9cb0cfa	remove special texture creation for fullscreen colormaps. ... On GL 3.x+ this isn't needed at all and on older hardware it causes performance issues, in particular with hires textures due to impossibility of precaching. In addition it forces some really awkward handling of lighting for things that have their own color, like stenciled sprites or particles. With this special case gone it will be possible to handle this case in a saner manner than it is right now. As compensation for older hardware a fullscreen blend will be drawn over the entire screen. This won't be 100% accurate but it's preferable to keeping the current method.	2014-05-11 14:46:37 +02:00
Christoph Oelckers	09f4071436	Ok, it had to be done: Removed shader support for pre GLSL 1.3/GL 3.0 hardware. The compromises needed to accomodate these are just too bad and would block any attempt at streamlining the code.	2014-05-11 13:27:51 +02:00
Christoph Oelckers	917a869a54	- fixed: gl_SetFog set the vertex attribute for software lighting mode without checking if the mode is actually on.	2013-12-23 09:56:16 +01:00
