- Removed colormap parameter from many functions.
removed all colormap references from texture management code.
- merged the colormap shader into the main fragment shader.
- all fixed colormap handling is now done at the start of each frame, no more manipulation of other data during processing (WIP.)
- made inverted sprites for Infrared and fog layer fixed colormap effects to reduce their overhead.
- with the new fixed colormap it is finally possible to handle the sky caps without messing around with the light values.
-removed all references to colormaps in the rendering code, aside from places where it's used to decide how to render an element.
- removed some remaining colormap stuff.
