C.5 Texture Replace Environment

A common use of texture mapping is to replace the color values of generated fragments with texture color data. This could be specified only indirectly in GL version 1.0, which required that client specified ``white'' geometry be modulated by a texture. GL version 1.1 allows such replacement to be specified explicitly, possibly improving performance. These additions match those of a subset of the EXT_texture extension.
