Finesse engraving for guitar bends

[bkunda]

This issue contains a checklist of finesse tasks for the most recent guitar bends implementation (#19746).

It will be continuously updated.

To do

• Improve horizontal spacing for double (and triple)-stop grace note bends to chords See video
• Adding bends to range selection chord causes extreme multiplication of bends See video
• Changing note value at the start of a bend should delete the bend See video
• Vertical arrow for pre-bends on chords collides with tab fingering

• Collision avoidance required for pre-bends and slurs:

• Improve default content scaling for new bends icons in palettes

Current

Desired default scaling

Proposed interaction constraints

(Not necessarily bugs, but constraints to prevent janky engraving for unplayable circumstances)

• Allow no more than one grace note bend or pre-bend on a single note See video
• Disallow slight bends on regular bends

• Disallow pre-bends on regular bend arrival notes

• Disallow pre-bends on main notes preceded by a grace note bend

• Follow slur rules with regard to direction; in case of mixed stem direction, bend should go above. Currently:
