Styling Y-position for rest symbols
Please consider adding styling options for rests. It would be particularly useful for guitar TAB so that rests could be vertically aligned with the rhythm stems. To achieve this it would need the Y-position to be styled with a value which would be applied as a negative for rests above the stave and a positive for those below.
It would also be useful to specify small size rests in styling.
Workaround: this can be done manually.
