a suggestion on this.....how about having about 5 or six pixmaps with
increasing amounts of their pixels shaded to black...the rest to transparent?

then you can overlay these pixmaps..depending on how far from the light source
over the other xpms.....

Doesn't even necessaryly have to be black...could be grey......

We have done some coloring here to make things like ghosts...spheres...look
somewhat transparent..by mixing transparent throughtout the body of the object
It seems to give a dimming effect to the pixmap underneath....might be something
to try.
