Grazie Andrea for pointing to the rasterization algorithm - what I was playing with was very different, a recursive bisection thing that was lots of fun to write but likely 100 times less efficient ;-) I'll give this a spin this week and will post my results. I need both algorithms to work reliably for well-behaved cases in a couple of months, so that's my timeline. If at some point anyone decides to take them up for integration in geotools, let me know so I can use the geotools version and stop playing with them in my own codebase. Again, I'm all but a GIS guru so my choices will need careful review.
I'll make sure to mention at least the known authors/contributors in the credits - if it comes from the original Grass the root authors were probably either Jim Westervelt or Mike Shapiro. Both old friends - I'll look at the grass source and if it's still unclear, I'll shoot them an email.
