This operator imports a polygon with holes, a general polygon, or a general polygon with holes from the input stream in.
An ASCII and a binary format exist. The stream detects the format automatically and can read both.

The format consists of the number of curves of the outer boundary followed by the curves themselves in counterclockwise order.
