The initial physics sprite is drawn at the line origin.

The first thing in the look is to add "inc_x" and "inc_y" to the location, so it
won't draw in the same place.

That being said, the two ends of the line are not being 
drawn in exactly the same way, so there is certainly a bug
here somewhere (just a minor discrepancy between the physics
and drawing).
