SMuFL name mapping update, 9 July

[Owen Lamb]

Hi all!

A bit of news on the SMuFL front. I've dropped in the next few 
Emmentaler categories (Default Noteheads, Special Noteheads, and 
Shape-note Noteheads), so feel free to give it a look at 
https://wolfgangsta.github.io/emmentaler-bravura/. Please let me know 
what you think, especially regarding the red "contentious" cells!

I whittled away at MetaPost and have discovered that the code for our 
two and seven number glyphs are allergic to being used more than once in 
a font, whether by literal duplication or by referencing them in a 
vardef twice. So, making a smaller variant set of our number glyphs is 
gonna take more work than anticipated. I decided to put it on the back 
burner for now, since it was holding up work on the encoding in general.

In case you missed the first round, it's still there! I made a couple of 
tweaks based on some suggestions from the W3C Music Notation Community 
Group, but otherwise not much has changed.

Regards,
Owen Lamb
