This modifier is actually ignored by the genprops.awk script. Currently,
a, o and O modifiers are ignored, because of the uniformization of
the property code; all set_xxx methods performs assignment from
octave_value. These flags are probably not needed anymore.

Concerning the patch, it looks good. What's then needed now is some
"behavioral" code to react to some property changes:
- face-vertex to X-Y-Z representation conversion and the otherway around
- automatic computation of the normals
- setting vertexnormals manually should set normalmode to true
If you're willing to do it, please go ahead. I implemented these kind of
things in JHandles, so you might want to take a look.
