Another example is: http://blahbleh.com/molecools.php?name=1,2% 20dimethylcyclopropane If you turn the molecule a bit, the circles disappear with a INDEX_SIZE_ERR exception. Isn't it better to just ignore the arc and go on with the drawing, like Firefox does? And perhaps the same for arcTo?
Assuming that we desire a "do what I mean" approach, it seems sane to me for a negative radius to be normalized to a positive radius with the same magnitude.
It goes from being the distance from the center to the edge to being the distance from the center to the "opposite" edge.
You might also like to visualize this as drawing the "back" of the circle.
