Description
The algorithm under subdivide is actually stupid, full of overthought false economies. A simpler approach is both faster and shorter (codewise). Don't worry about creating interim geometries you have to throw away, working against smaller geometries will more than pay for itself.
Note:
See TracTickets
for help on using tickets.
Done at r13804. On basic test, ran about 20x faster. Seems like a winner.
