+ This function performs boolean operations between two polygons
+ using the Greiner-Hormann algorithm
+ (http://davis.wpi.edu/~matt/courses/clipping/).
+
+ SUB is a two column matrix containing the X and Y coordinates of
+ the vertices for the subject polygon.
+
+ CLIP is a two column matrix containing the X and Y coordinates of
+ the vertices for the clipper polygon.
+
+ OP is a text string containing the operation to perform between
+ SUB and CLIP. Possible values are:
+
+ * 'AND' Intersection of SUB and CLIP (value by default).
+
+ * 'OR' Union of SUBT and CLIP.
+
+ * 'AB' Operation SUB - CLIP.
+
+ * 'BA' Operation of CLIP - SUB.
+
+ For the matrices SUB and CLIP, the first point is not needed to be
+ repeated at the end (but is permitted). Pairs of (NaN,NaN)
+ coordinates in SUB and/or CLIP are omitted.
+
+ X is a column vector containing the X coordinates of the vertices
+ for. resultant polygon(s).
+
+ Y is a column vector containing the Y coordinates of the vertices
+ for. resultant polygon(s).
+
+ NPOL is the number of output polygons.
+
+ NINT is the number of intersections between SUB and CLIP.
+
+ NPERT is the number of perturbed points of the CLIP polygon in any
+ particular case (points in the oborder of the other polygon)
+ occurs see http://davis.wpi.edu/~matt/courses/clipping/ for
+ details.
