WMS with EPSG 21781 draw wrong

[znarf1965]

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.
