Joshua was faster than me, but I came up with the exact same code. This
is how:
1. Type "bezier" in a Workspace, select it, press ctrl-w. There I found
Bezier2Segment.
2. Browsed the class side of Bezier2Segment and found method
#from:to:via.
3. Brought up a protocol browser on Bezier2Segment, restricted
inheritance to LineSegment and found debugDraw. Look in that method to
see the details.
