Examples
AddPolygon(xxyy;50 50 150 150 150 100 50 250)
AddPolygon(xyxy;50 50 150 150 150 100 50 250;blue)
Description
The AddPolygon() function makes it possible to draw polygonal areas whose fill, border and shadow can be varied. The argument scanDirection makes it possible to enter coordinates in two ways: either all x-coordinates are entered first and then all y-coordinates (scanDirection = xxyy) or the x and y-coordinates of the 1st polygon point are entered, then the x and y-coordinates of the 2nd polygon point, etc. (scanDirection = xyxy). All coordinate values are to be entered separated by spaces, tabs or line feeds.
