The test is updated and somewhat expanded.

Sql Server System Types seems very good while Geos is not doing well.
Maybe there are problems with my code but with big polygons its memory
usage is very high (more than 3GB with 723347 input vertices). I also
tried to load polygons from wkt files, bypassing the C++/Cli wrapper,
but the memory usage is the same.
