10770	[Patch] save coordinates in current map projection	TobWen	simon04	"Since JOSM supports multiple map projections with the plugin ""proj4j"" and since it supports output in GeoJSON and GPX, it would be nice to export coordinates in the current map projection.

When working in EPSG:31466, coordinates get transformed back to EPSG:4326 on export. Since the transformation isn't perfect, errors are growing. Sure, that's not important for OSM, but JOSM can also be used outside of OSM.

GeoJSON, GPX and other formats support different map projects, so it would be nice to see an expert settings to switch from geographic coordinates to map coordinates."	enhancement	closed	normal	15.10	Core		fixed
