Infinite ledger lines in MusicNotation

[MarkOates]

When running visual tests on the Intel MacOS, the MusicNotation had like 100 ledger lines going down on each note.

I had a quick look over the code, thinking it could be a missing or uninitialized variable in the initialization list, but the quick skim didn't reveal anything. I might have overlooked it. Either way, I didn't find the cause right away and continued on higher priorities.
