Use Coords2Angles to convert the coords for Start and End Radial-Points, such as are used in the Windows API Arc Pie and Chord routines, into an Eccentric (aka Radial) counter clockwise Angle and an Angle-Length, such as are used in X-Windows and GTK.
The angles angle1 and angle2 are returned in 1/16th of a degree. For example, a full circle equals 5760 (16*360).
Zero degrees is at the 3 o'clock position.
