/* The ARB_bindless_texture spec says:

 *  GetTextureSamplerHandleARB) is not one of the following allowed values.
 *  If the texture's base internal format is signed or unsigned integer,
 *  allowed values are (0,0,0,0), (0,0,0,1), (1,1,1,0), and (1,1,1,1). If the
 *  base internal format is not integer, allowed values are
 *  (0.0,0.0,0.0,0.0), (0.0,0.0,0.0,1.0), (1.0,1.0,1.0,0.0), and
