SMuFL name mapping update, 17 March

[Owen Lamb]

Hi all,

I've finished mapping the last five glyph categories: Mensural, 
Neomensural, Petrucci, Solesmes, and Kievan. Of those, only the Mensural 
and Neomensural glyphs provided much trouble, but as always, extra pairs 
of eyes are encouraged to spot typos and other mistakes or give 
suggestions throughout the database.

The link to my work: https://wolfgangsta.github.io/emmentaler-bravura/

A couple details showed up in the Solesmes and Kievan glyph mappings 
that caused me to change a few decisions in the Vaticana section as 
well, so be sure to check out the contentions and annotations there.

This leaves the following outstanding tasks (I'd update the to-do list 
on the Github wiki, but I keep getting an error when I try):

Proposed deletions:
* noteheads.s1(do|re|mi|fa|sol|la|ti).* (redundant glyphs; in all cases 
identical to s0)
* scripts.trillelement (unused; scripts.trill_element is used instead)
* scripts.augmentum (unused; dots.dotvaticana is used instead)

I think the deletions can be made in a simple commit at any time, adding 
a few glyph replacements to convert-ly. If I'm free this week, I'll put 
an MR together.

High priority issues (I'd like to get these done before I begin 
integrating my GSoC work):
* A glyph should be created for SMuFL's clefChangeCombining character.
* noteheads.[uds][0-2].*(Funk|Walker): There's... still a lot to sort 
out here. I'll give it another pass, but I'd rather not get too hung up 
over it.
* scripts.arpeggio(.arrow.M?1)?: I think we'll need to create rotated 
copies of these glyphs to satisfy SMuFL, which means the current glyphs 
as they stand should get unique names that don't match any current SMuFL 
glyph.
* scripts.pralldown: Some more research is in order--is this 
functionally identical to SMuFL's ornamentPrecompTrillLowerSuffix?
* Contentions in this session's work (Vaticana edits plus Mensural, 
Neomensural, Petrucci, Solesmes, and Kievan): please let me know if you 
notice anything or have suggestions!

Once these things are straightened out, I'll dust off my GSoC code, 
using the data here to create a SMuFL version of Emmentaler and give 
LilyPond SMuFL support.

Low priority issues (Nice to do, but can wait until after GSoC integration):
* A small numeral set should be created so non-LP programs can print 
fingerings easily.
* noteheads.[ud]M2: It would be nice if the stems weren't hardcoded.
* It might be nice to add a set of combining strokes for custom trill 
composition.
* pedal.Ped: Looking again at this, I'd sure love to call the SMuFL base 
glyph keyboardPedalPed a ligature [keyboardPedalPedNoDot + 
keyboardPedalDot]. But I'm worried that if someone enables a styleset to 
automatically correct keyboardPedalPed to keyboardPedalPedNoDot, then 
we'd have an infinite loop in ligature/alternate evaluation. Thoughts?
* accordion.oldEE: This may have to remain a mystery, but I'll ask one 
more time: has anyone seen this thing in accordion literature before??

See you next time,
Owen Lamb
