geometry and projection with WFS

[Steve Lime]

Probably just an oversite. I'll try and address tonite before rc1...

 From what I can see the problem seems to be that the gml code assumes 
that when a shape object is projected from layer to map, the shape bound 
in the object in also reprojected.  It uses the function msProjectShape. 
This function does not reporject the bound. I do not know why.  I added 
locally a call to  msProjectRect(in, out, &shape->bounds); and It seems 
to solve the problem. Is the bound always valid, are there reasons not 
to reproject the bounds ?
 
Bug http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=1586 has been 
entred on this.
