Description
As I'm porting topology function down to liblwgeom I feel the lack of accessing the nice RTree optimization used by ST_Contains when called with point and polygon inputs.
Those optimizations only exist in the PostGIS side of things, due to lwgeom_rtree.h and friends being only there.
It would be nice to migrate them, after defining a clean API.

Maybe. There's already some unused local acceleration code in the lwgeom_tree code line, waiting for use in distance acceleration. It could equally be used by p-i-p acceleration too. I would probably make the p-i-p code use that, rather than the range-based code currently in ./postgis.
Note:
See TracTickets
for help on using tickets.
It seems that there are quite a few things in the postgis/ side that don't depend on Postgres and could be moved over to liblwgeom/ .
Is this something we want to pursue in general?
