Shapefile.

When I select the geoms on the map, I see the selection as if it's been 
transformed from screen to real world coords. (The effect is, for 
example, the geoms around 7°W,50°N apeear at pixel position 7,50.) Looks 
like the affine transform is not (or wrongly) set. Is the selection a 
layer of its own?

Cheers,

Ugo
