It's true that pic does not write PostScript, but this is not to say
that you can't get shaded shapes in your troff'ed document.

There should be a way in your pic/troff doc to pass instructions directly
through to the printer (i.e., the PostScript, imPress, or whatever interpreter)
I've used SoftQuad's sqtroff and they have macros that allow you to insert
and position EPS (Encapsulated PostScript) files within your troff file.

What this means is you can draw whatever you want in a PostScript program,
and then insert it into your troff. I know you can do the same thing with 
imPress (I've seen this in the Imagen manuals), but I haven't tried it.

Hope this helps.
