There were a few bugs in the
point_in_polygon()
routine added in #1407 (off-by-n errors and premature termination). The test included in that PR was only a very basic case (unit square) and so did not catch these. Fix the issues and add test cases for other geometries:Tests are also refactored a bit for easier future expansion and nicer messages on failure
