Improve tremolo slants

Issue type

Engraving bug

Bug description

There are still occasions that tremolo bars between notes are forced horizontal.

This seems to happen if one of the two notes is of certain pitch (or stave position*). In such cases, if the other note goes higher/lower than the said note in the opposite direction of the stem, the tremolo bar will always stay horizontal.

I believe it is these 6 notes:

Even more broken on shorter notes. Note the beam that shifts up and down but always refuse to be slanted:

Additional issue -- If both notes have ledger lines and are on the same side of the stave, the tremolo bar slant angle is too small**

However, it will fix itself once the positioning of the tremolo bar is adjusted.
