It wants a PROJ.4 projection string.  Perhaps it should accept the same
codes that *cs does.

Really you want to just specify the coordinate system in the .svx file
though - that way it's included in the 3d file and automatically used.
The field to specify it is just there so you can export from old 3d
files from before the coordinate system support was added.
