Note: the glprefs data used can be summarized by the related function
glprefs_data_used_by_setup_standard_lights (which see).
Warning: has side effects on GL_MODELVIEW matrix.
Note: If GL_NORMALIZE needs to be enabled, callers should do that
themselves, since this depends on what they will draw and might slow down
drawing.
