[geos-devel] Possible speed improvement for overlay operations

[Paul van der Linden]

Ok, you're right. This was just a random example I used to see if I can
spot some improvements and get a bit of a feel about the algorithms used.

Ultimately I'm trying to figure out if the overlay-ops (especially
intersection and union) can be reworked to use prepared geometries, but
will make sure any tests I do involve real-world polygons
