Specifies the coordinates of the four corner points of a quadrilateral defining the overlay area. Exactly four coordinate tuples have to be provided, each consisting of floating point values for longitude and latitude. Insert a space between tuples. Do not include spaces within a tuple. The coordinates must be specified in counter-clockwise order with the first coordinate corresponding to the lower-left corner of the overlayed image. The shape described by these corners must be convex.
