The function ReducePolygon removes all superfluous points of the polygon specified by the paramter Polygon. A superfluous point is one which does not change the outline of the polygon (i.e. a point which lies exactly on the line spanned by the two neigbouring vertices). The function returns the number of the remaining vertices, the variable parameter Polygon is resized accordingly.
