 There is an issue on rendering WMS on EPSG 21781.
 In general when using standard EPSG 4326, MGOS/AIMS they both draw well
 (but slow).
 But when using EPSG 21781, MGOS/AIMS they both draw very bad and sometimes
 totally wrong.

 I use the following WMS for test (but I get exactly the sme result for all
 swiss WMS)
 http://webgis.uster.ch/wms/admin/administrative_grenzen?version=1.3.0

 I prepared a simple example that shows the problem.
 - Map Library://Test/Default.epsg21781.MapDefinition draw polygons in
 grey.
   This map has original coordinate generated by Map3D
 - Map Library://Test/Default.epsg21781.MapDefinition draw polygons in grey
 again.
   This map has EPSG 21781 with WKT got from "translate" tag in
 OgcWmsService.config.owt
 - Map Library://Test/Default.epsg4326.MapDefinition draw polygons with
 right colors.

 The problem is serious because there is no possibilities to read WMS with
 this coordinate systems and this make AIMS/MGOS not usable in many cases.
