nanogui: Thread: Re: GrArc() function doc update [part deux]

Hi again,

Changed the value below from -25 to -2500 had no visible change.

So, could someone please correct my understanding if wrong:

Points a & b are used to calculate a vector from the origin of the arc to
indicate where the arc starts and stops.
