There's nothing built into the slider widget for changing
the "knob" of the slider, sorry. Also, non-rectangular
areas have a tendency to become a PITA for updates etc.:-(
But feel free to derive your own customized object type
rom the slider type. As far as I can see the files for
the slider class are slider.c and sldraw.c.
