I solved my problem for now by changing my approach to the pie chart and using solid color for the circle, then I filled one small segment by drawing short, straight lines a few points wide before drawing over the entire thing with an outer dark circle and the various radii. It works well for what I need right now, but the macro approach makes sense provided groff supports sine, cosine, and tangent functions...
I'm getting some really awesome looking slides, though they're a bit laborious -- mainly because I haven't taken the trouble to try to come up with more elegant macros which I really don't need all that badly. The ones I have cover much of the tedium. Thanks for your inputs, all.
