| 19:51 | Provide the two-argument geopoly_within(P1,P2) routine that determines if polygon P2 is contained within polygon P1. Make this function available to the query planner for optimized rtree lookups. Update the visual01.txt script to verify that the new functionality actually works. check-in: 6eb5d09b user: drh tags: rtree-geopoly | |
