Adds a polygon to the current page. The polygon is drawn in the
current color at the
current width and with the
current options. The
polygon may be outlined or filled.
The points string is a sequence of numbers representing the
coordinates of the polygon. The string should be of the format "x1
y1 x2 y2 ... xN yN". The numbers may be delimited with spaces,
commas or semicolons. If the first point is equal to the last then
the path is closed before outlining.
The AddPoly method returns the Object ID of the newly added
