Yes that reveals more of what the problem is
at the -180 you get an arc with the radius on the
wrong side of the line. It makes almost a full circle
this is what you would get if you had a negative
radius greater than the inverse of the lowest radius
that would also explain why it disappears I'll have to
look at the math again.
I think i'll also try the eponymous Bresenham's circle algorithm
to draw the circle

I just said eponymous cause it fit and it's fun to say :p
Thanks for the input
