How do I change the style for the TAB clef

[therealsujitk]

I don't really like how the TAB text looks on the stave, is there a way I can make the font bold and maybe scale the size down a tad bit? Setting the size to 'small', is too small for me and using Clef.setFont() doesn't seem to have any effect.

I noticed the tests have a different font for this text, but I couldn't figure out how this was done.

I found calling Vex.Flow.setMusicFont('Leland'); makes this font bold, but I'd still like to scale it down a bit, especially for when I want to show fewer strings.
