### Description

The operation computes the area of a polygon bounded by a closed path. The area is measured in square pixels. As paths in FIS are subpixel-precise, the result may be (and usually is) non-integer.

Note that if the input path is not a valid polygon (i.e. it has at least one self-intersection), the computation may lead to results that are not intuitive.
