Title: #13108 updates

Replaced beam by flag for single grace note
Fixed "pixel dust" by setting bbox

Note that adding an embellishment of three or more grace notes results in a divide by zero in the beam layouter. This is not related to my changes, it also happens when using the regular grace note palette to add three grace notes to one normal note. Will submit an issue and (try to) investigate.
