Circular arc. Has a rotation counter to allow rotation deltas greater than 360 degrees and less than - 360 degrees. The CArc is intended to function as closely as possible to the functioning of CArcTails in a curve path. Hence, the decision to store the three points as fields rather using the AngleVec of the arc which would allow less data. This is to avoid calculation / rounding errors in the start and end points, which will be used by other CurveSegs in curve paths.
