JOSM not usable at polar regions

[flomigulau]

I want to add some features in the surrounding of the South Pole, but JOSM is not able to handle this.
E.g.: try to add ceremonial South Pole Marker at -89°59.95' / -037°42.15'

To my mind the best solution is to implement the Stereographic Polar projection, but any other enhancement is welcome.

If you need a GPX file of this region, please contact me (I am a registered OSM user).

Switch from Mercator to EPSG:4326 projection. This one is able to handle polar regions.

You see supported parameter range in the projection settings page.
