A quick, "shoot from the hip" suggestion -- why not just load a new
stippled Pixmap? That's probably the most straightforward method.
Another quick thought -- if you're using Xpm Pixmaps, you might try
fiddling with the shapemask. You could use a stippled mask.
There might also be games you can play with the GC (Graphics Context)
but how you get at the right one would take some digging, I fear.
These are just quick and dirty ideas. When I get a few minutes to
play around, I'll see if I can come up with more concrete suggestions.
