 I see.
 The bias and scale of glPixelTransfer is done when the pixels goes through
 the Geometry Engine.
 Another option is available for textures only, on a per-texture basis and
 may be of interest for you:
 GL_POST_TEXTURE_FILTER_SCALE_SGIX and GL_POST_TEXTURE_FILTER_BIAS_SGIX
 of glTexParameter.
 This let you change the parameters without having to reload the texture image.

 Best Regards
