[OSGeoLive] Proposing t-rex vector tile server

Thu Jun 13 04:29:05 PDT 2019

Sorry for the delayed response. I was just searching my emails, and 
can't seem to find anywhere where someone has answered our OSGeoLive 
project selection criteria. It would be good to make sure that we have 
all our usual criteria ticked off before adding it in.

I suggest that someone make sure these questions are answered before we 
include t-rex into OSGeoLive.
