OGSF library - loading and manipulating surfaces (higher level functions)
GRASS OpenGL gsurf OGSF Library
Plans for handling color maps: NOW: if able to load as unsigned char, make lookup table containing palette otherwise, load directly as packed color, set lookup = NULL MAYBE LATER: if able to load as POSITIVE short, make lookup table containing palette
