added glyphs:

• 4stringTabClef
• fermataLongHenzeAbove
• fermataLongHenzeBelow
• fermataShortHenzeAbove
• fermataShortHenzeBelow
• breathMarkTick
• breathMarkUpbow
• caesuraThick
• caesuraShort
• breathMarkSalzedo

fixed glyphs:

• fixed scaling in timeSigParensLeft
• fixed scaling in timeSigParensRight
• fixed position of octaveParensLeft
• fixed position of octaveParensRight

Also this updates the metadata file, which before was just a copy of the metadata file coming from Bravura. Now it contains the correct bounding box informations.

Why is the change to fonts/gootville/metadata.json so huge? More than 36.000 deleted lines?
Does that reflect the relative incompletness vs. Bravura?

[rettinghaus]

Basically yes. It now only reflects the glyphs actually contained in the font.

[Jojo-Schmitz]

I guess the vtest differeneces are to be expected?
Almost all look pretty small and harmless except maybe the one for ornamets?

[Jojo-Schmitz]

@rettinghaus maybe you'd like to check https://musescore.org/en/node/319778, esp. the part of the issue with the gap, apparently cause by your changed to the engraving defaults, esp. those for stemThickness (0.12 to 0.076) and staffLineThickness (0.13 to 0.08)
Then there's also https://musescore.org/en/node/319636 which seems a regression from your changes in this PR?

[rettinghaus]

@Jojo-Schmitz I think these are different issues. Making the stemThickness actually smaller should not make them stick out the notehead. But the anchor points were missing in the updated metadata.json, so I added them back in and reversed the changes in the engravingDefaults. See #8082.

[Jojo-Schmitz]

Does #8082 fix https://musescore.org/en/node/319778 and/or https://musescore.org/en/node/319636 ?

[Jojo-Schmitz]

Yes, it does...
