oh trifill only fills a the triangle with color?
heh that's easy then

I'll add it. for now just connect 3 lines and use ordinary paint command to fill the are with color.

That won't work if there's stuff behind the triangle - you need to walk down the left and right legs of the triangle and raster a line at a time. (Of course, you probably already knew that, but... )
