TEXMAP addition to Official Library Spec

[Orion Pobursky]

Is there an overview of which viewers and editors that cannot handle Texmap? Adding fallback geometries can be a great amount of work, so I'm considering if it will be easier to simply update all viewers.

We have open source code for Texmap -> UV translation, so porting this code to the various editors might be a good choice.

I think MLCad is the only major outlier and it will probably never be updated. There are, however, quite few minority viewers/editors that will probably never be updated either. Most of those don't recognize the !COLOUR meta either so they can't rightly be said to follow the spec.
