[Tile-serving] [mod_tile] UTFGrid support (#34)

[Andy Allan]

It would be great to support UTFGrid generation using renderd and mod_tile.

https://github.com/mapbox/utfgrid-spec

An example UTFGrid-enabled mapnik xml file is at https://gist.github.com/gravitystorm/5824793

I'd suggest that it's a per-layer option to also generate the UTFGrid at the same time as the png (or other raster) output, and expire them as a pair. However, I can see there being some (rare) usecases where you may wish to generate UTFGrids without a corresponding png output.
