 polylabel provides a fast algorithm for finding polygon pole of
 inaccessibility, the most distant internal point from the polygon
 outline (not to be confused with centroid). Useful for optimal placement
 of a text label on a polygon.
 .
 It's an iterative grid algorithm, inspired by the paper by
 Garcia-Castellanos & Lombardo, 2007. Unlike the one in the paper, this
 algorithm:
 .
  * guarantees finding global optimum within the given precision
  * is many times faster (10-40x)
