Use the pfuPath routines in the pfutil lib.
If you want ground clamping you can use node intersections to
determine height and orientation.

Use an image edit tool like the texture editor of Multigen.
I don't know another one that can edit the alpha plane.

The source of the pfiXformer are available in
    /usr/share/Performer/src/lib/libpfui
so you can adjust them to fit another input device.
