Less space than before for Genre in Tag Panel

[Florian]

I've added the Tag-Panel field size Smaller (i.e., smaller than Small) with Mp3tag v2.91c.

Out of curiosity, how difficult is it to implement such a new size?

I won't go into the implementation details here. Difficulty is all relative and I don't see any benefit in going into this.
