// Neal White III - 12-28-1999 - OpenGL fullbright bugfix
// [email protected]
// http://home.telefragged.com/wally/
//
// Problem:
//
// There was a problem in the original glquake with fullbright texels.
// In the software renderer, fullbrights glow brightly in the dark.
// Essentially, the fullbrights were ignored. I've fixed it by
// adding another rendering pass and creating a new glowmap texture.
//
// Fix:
//
// When a texture with fullbright (FB) texels is loaded, a copy is made,
// then the FB pixels are cleared to black in the original texture. In
// the copy, all normal colors are cleared and only the FBs remain. When
// it comes time to render the polygons, I do an additional pass and ADD
// the glowmap on top of the current polygon.
