gl2 is maintained but no longer developed I'd say.

No, at least I won't accept such special purpose code in vo_gl. If you
go with my suggestion below, you can add these as PARAMs in the vertex
program code (which will be a seperate file).

IMHO, implement support for vertex program in the vo, thus not
introducing such special-purpose code into vo_gl. That means you will
have to e.g. extend glDrawTex to use more than one quad.

That would be me.
