-## Convert a circle arc into a series of points
-##
-##   P = circleArcAsCurve(ARC, N);
-##   convert the circle ARC into a series of N points. 
-##   ARC is given in the format: [XC YC R THETA1 DTHETA]
-##   where XC and YC define the center of the circle, R its radius, THETA1
-##   is the start of the arc and DTHETA is the angle extent of the arc. Both
-##   angles are given in degrees. 
-##   N is the number of vertices of the resulting polyline, default is 65.
-##
-##   The result is a N-by-2 array containing coordinates of the N points. 
-##
-##   [X Y] = circleArcAsCurve(ARC, N);
-##   Return the result in two separate arrays with N lines and 1 column.
