Summary: Add st_tri → [raster] Add st_tri

Can I get some reference material describing TPI and TRI? That way appropriate regression tests can be created. I can't really consider committing this without a good understanding of the operations and verifying that the code is doing what it is saying it is doing.

We also need user documentation and it is technically your responsibility to provide regression tests as well but we'll help you :)

Please refer to patch submission guidelines section in wiki http://trac.osgeo.org/postgis/wiki/DevWikiMain

-- Which has these links (I admit we probably need to update those so if anything is unclear just let us know)

Milestone: PostGIS 2.1.0 → PostGIS Future

No regression tests or docs... punting to the future. Should also add roughness...

Added docs, is there anything other than regression test that I need to do?

Thanks,
