For packaged TileMill on osx and windows we include the proj4 and gdal libraries. Each need supporting csv files carried through for full function.
We should choose a good place to keep them and make it consistent on both osx and windows. My first thought was tilemill/data but that appears to be automatically moved to ~/Documents/MapBox/cache/data upon start.
So, what is a good place? Discuss...
What are the supporting CSV files for? I've never seen these before.
The stuff you have in /usr/local/share/proj and /usr/local/share/gdal. Proj needs this as per #560 and gdal needs them to read certain kinds of geotiffs. Also node-srs, if linked to gdal (which it is on windows), absolutely must have them to function.
Hrm, we should def. keep these within the tilemill application. Let's keep using data for now? We can just make this copy operation smarter:
Such that only the shapefile data is copied to documents.
Selectively copy sample data file to MapBox/cache dir. Refs #1114.
