Previous typing was confusing the compiler. It could not figure out the
difference between the proj4 property and the constructor, which lead to
errors such as:
- ol.proj.setProj4(proj4)
ERR! compile /home/gberaudo/dev/ngeo/src/proj/epsg21781.js:8: ERROR - actual parameter 1 of ol.proj.setProj4 does not match formal parameter
ERR! compile found : function (new:proj4): ?
ERR! compile required: (null|proj4)
ERR! compile ol.proj.setProj4(proj4);
ERR! compile ^^^^^
- ol.proj.proj4.get().defs('EPSG:21781', epsg21781def)
ERR! compile /home/gberaudo/dev/ngeo/src/proj/epsg21781.js:26: ERROR - Property defs never defined on proj4
ERR! compile ol.proj.proj4.get().defs('EPSG:21781', epsg21781def);
