I suppose its possible, but I don't think it's worth the disruption
in order to tell people that they are doing something really stupid.

Do you mean the rightmost point? You can draw a line using
obj.drawLine(100, 100, 50, 50), which will draw a line from (100,100)
to (50, 50). You can draw the exact same line using obj.drawLine(50,
50, 100, 100). Now you change the Length property: in the first case,
the point at (50,50) changes, and in the second case, the point at
(100,100) changes. I don't think that that's a very good solution.
Line segments are specified using 2 points, or using one point, an
angle and a length. Currently we only support the former.
