-----------------------------------------------------------------
[~julianhyde] My future plan is to use calcite in baremaps to produce vector
tiles. Having JTS was a first step, but I'm interested in contributing
additional functions. Should I create one issue per function? Some of them may
be quite significant (e.g. ST_AsMVT, ST_AsMVTGeom, ST_TileEnvelope).

> The geospatial functions are currently implemented using the ESRI library. We
> should consider using JTS instead. AT the time we started work on geospatial
> the JTS did not have a suitable license, but this is no longer the case. I
> gather that JTS is a superior library.
