No error message with unknown text-face-name at POST /layergroup time

[strk]

Missing font face doesn't currently generate an error at layergroup creation time, unless geometries happen to fall in the "test tile" (CartoDB/Windshaft-cartodb#90)

It turns out there's a mapnik option to enforce text face checking at map load time (mapnik/mapnik#1791 (comment)).
We want to use that, for better error reporting. This will depend on tilelive-mapnik.

So it looks like the strict parameter in mapnik loader is hardcoded to false in tilelive-mapnik, so this would still hold us back to our own fork. Filed a ticket for the future in tilelive-mapnik: mapbox/tilelive-mapnik#74

For the record: switching to "strict" map loading resulted in some previously accepted style to become invalid.
See CartoDB/Windshaft-cartodb#93 for one example.

Reopening to deal with the backward compatibility issue. There's hope to do this in a different way: mapbox/carto#242

Closing again, after all the bug was fixed in 1.14.3, so the backward compatibility issue will be taken care of by #98
