Add stylistic alternate "violin clef" to the existing G clef

[dspreadbury]

Requested by Robert Piéchaud:

"There is one symbol that I cannot find in SMuFL, that is what (I think) is called a “violin clef”, a Renaissance version of the treble clef."

[Jojo-Schmitz]

Funny enough 'Violinschlüssel' is what Germans call a regular G or treble clef

[dspreadbury]

@mscuthbert Do you recognise this clef? Do you know anything about it? Do you agree that it should be included in SMuFL? If so, would you be inclined to include it in the Medieval and Renaissance clefs range?

[mscuthbert]

Yes, I think I see it more in early baroque than Renaissance music, I believe. I think it's an alternative stylistic form of the standard G clef. Here's a reference in: https://www.smithsonianmag.com/arts-culture/the-evolution-of-the-treble-clef-87122373/

A related version with G sign below it in Marenzio: (from 2nd New Grove under "Clef")

Here is the entry from Apel, Harvard Dictionary of Music, 2nd ed (1969). No date is given.

EDIT: I don't think it's called a violin clef (unless it appears on line 1 -- i.e., a third above treble). I would call it simply earlyModernGClef since we have disagreement on whether it's Renaissance or Baroque and that term mostly covers either. If it's Renaissance, it's late Renaissance.
