DrawSailAngles:

--------------------------------------------------------------------------
   Draw cone and clock angles in 3D using translucent patches in a new figure.
   Also draws the reference plane. Does not draw the sail itself.

   The reference frame is first rotated about +X by the clock angle and then
   the cone angle is achieved by rotating about the new Z axis. 
   The cone angle is drawn with a rad patch and the clock angle in green.

   Since version 7.
