Actually, I rolled my own version of eval_pigment by creating a pigment function
and then just calling it repeatedly as I moved along the palette jpeg.  I wasn't
worried about speed since this is something I do in the modeling stage rather
than the rendering stage.  (To be honest, I didn't look to see if there was
something built in to do this already...)
