At first, I would implement all RTREE supported operators in GIST.
Then, the GIST implementation may be a full replacement/alternative for RTREE.

Futhermore, I would implement all relationship operators, which are unsupported
in RTREE using GIST. As a consequence, the TODO item:

- Add rtree index support for line, lseg, path, point

can be marked as "done".
