Have filled polygons been considered as a pic capability? It appears that all the infrastructure is in place and only needs a simple syntax, like "poly from A to B to C".
I made a filled right triangle by editing out one corner of a box in pic output, and of course any polygon can be broken down into right triangles ... but this is madness. It it seems like a good idea, I might volunteer to try to do it right. Doug McIlroy
