Incorrect alignment of lines at the beginning of a system

I don't have any examples at hand to compare with, but it looks good to me.

BTW, a related issue that concerns me more:

If I create a whole note in 4/4 and attach a pedal marking to it, it extends to the end of the measure (I added that code recently). But if you have two half notes, it does not. That's because the position is set to allow pedal changes - the angled hooks - to align. And if you extend one more notch, it aligns to the first note of the next measure. It occurs to me we could check the hook type and differentiate layout based on that - align with start of note note for angled brackets, with end of note (or measure) for straight hook.

CombatCube: are you still thinking of submitting a PR for this? I've got working code for the check on hook type I mentioned above on pedal lines, not sure if I should wait you for or if you are already taking care of this or what.

Pedal segments: If a pedal segment starts at the beginning of the system, it should be just under its first note. If it continues into the next system, its continuation should be just before the key signature.

Actually, if the pedal mark continues on the next system, I think it should start after the key signature, not before:

Examples from scores:

Burnam - A Dozen a Day, Book Four (1964)

Bartók - Romanian Folk Dances, Sz.56 (Universal Edition, 1918)

Beethoven - Piano Sonata No.2, Op.2 No.2 (G. Ricordi & C., 1919)

Voltas: If a volta starts at the beginning of the system, its opening hook should be just before the key signature. If it continues into the next system, its continuation should also be just before the key signature.

Similarly, I think that it should be after the key signature. Examples:

Schumann - Album für die Jugend, Op.68 [Muzyka, n.d.(ca.1988)]

Beethoven - Piano Sonata No.13, Op.27 No.1 [C.F. Peters, n.d.(ca.1920)]

Schytte - Melodische Vortragsstudien in allen Tonarten, Op.159 (Wilhelm Hansen, 1909)

BTW, here is a link to the forum discussion that led to this issue being filed:

Heads up: I am planning to fix some of these continuation issues as part of my PR for pedal. At least pedal continuation, and whatever other lines would benefit from the same change. I'll let you know what I end up doing.

This includes my adjustment to pedal length as well as startpoint for continuation lines. Because the fix for pedal continuation ended up being the same fix needed for other lines such as hairpins and voltas, I went ahead and implemented it for them as well. All continuation lines for segment- and measure- anchored lines would now start right after the clef/keysig/timesig. And I change the regular startpoint for voltas as well.

Here are the vtests for my proposed fix:
