Yes. We should allow one format and one format only. PNG is probably the right choice.
However, the more I think about this, the more I'm leaning more towards just distributing images alongside the model file and not embedding them. The original reason for this meta was to embed unofficial textures in OMR models and I'm starting to become unconvinced that we need a new meta to do something that is solved just by distributing an extra file.
