Given two angles (the starts and end of an arc), e.g. 90 degrees to 180 degrees, I need to output the starting and ending degrees of a small arc, and a large arc.
In this case the small arc is simply 90 to 180 (no change needed). The large arc would be 90 to -180.
45degrees -> 270degrees Small: 45degrees -> -90degrees Large: 45degrees -> 270degrees (no change from original)
I originally thought that subtracting 360 from one of the angles would work, but it doesn't seem to work in all cases.
