  Easily. Specify a color_map with some of the values being rgbf 1

  You should have tried the same thing with other objects. Your conclusion
that it's a problem with image_maps was too premature.
  As Nathan said, it's not a problem with image_maps, nor meshes. It's not a
problem at all. It works as it should.
  (Why? If not, how would you make clear glass with highlights?)
