On this matter, my status = 0%, and I agree with the proposal.

Also, as we are on the verge of adding quite a lot of new properties,
Don't you think we should "upgrade" the property adding code? What I
had in mind is something like the genprops.awk script, but it would
also need to generate:

properties::properties (const graphics_handle& mh,const graphics_handle& p)
properties::get(void)
properties::get (const caseless_str& name)
properties::set_defaults(void)
properties::set (const caseless_str& name, const octave_value& val)
properties::factory_defaults (void)

I am not very proficient with awk. would be it possible to this in
awk? If not, I can try to do it in perl. Is that acceptable or is perl
not a dependency of octave?
