Gets or sets the list of points used to define the polygon inside the SignatureLine where no text can be drawn.
A minimum of 3 points are necessary in order to activate the WrapPolygon. By default, null (unless the SignatureLine's WrappingStyle property is set to WrapTight or WrapThrough, in which case it will contain the 4 corners of the picture by default, meaning no text inside the SignatureLine).
This property is used when the SignatureLine's WrappingStyle property is set to WrapTight or WrapThrough.
The top left of a SignatureLine has the coordinates (0,0), while the bottom right has the coordinates (21600,21600).
