* Fix SkPath::arcTo when sweepAngle is tiny and radius is bigGravatar xidachen2016-10-06
| | | | | | | | | | | | | | | In this function, it first check whether this arc is a lone point or not. If not, it converts angles to unit vectors. The problem here is that when the radius is huge and the sweepAngle is small, the function angles_to_unit_vectors() could return a startV ==stopV. When that happens, it will draw a dot at the point that corresponding to the startAngle. This CL adds a special branch for this case, and draw a connecting line between the points at startAngle and endAngle.
