[Qgis-developer] New feature's needed, create geometry from attribute

[Nathan Woodrow]

I don't think VRT would work because not all QGIS data sources are OGR
based so VRT wouldn't work in that case.

A special type of layer, e.g plugin, IMO would be best for this. Something
that just reads the feature from the underlying layer and adds the geometry
on the fly.
