That's a pretty good idea.  The kind of feature that, well done, would
shake the open source modeling community.  Don't know how easy that
would be, though.

Blender converts the mesh data to the "E" type, where verts/faces have
flags to indicate whether they are selected, etc.  Having a new "WMesh"
mode for winged edge structures seems to fit nicely.

Only thing (just something users would have to get used to) is that a
winged edge representation doesn't like lines and isolated vertices, but
its possible to "convert" from normal Blender representation to that and
back, of course.

We should really consider Chris' suggestion...
