ottava engraving issues
There are several engraving issues I have encountered with ottavas.
Symbol should be aligned just left of the first note it affects, not centrally (can be manually overridden)
Line should be vertically aligned with top or bottom of symbol depending on whether it is 8va or 8vb (can be manually overridden)
Hook should be solid, not dashed, even if line is dashed (no workaround!)
Hook should be shorter (partial workaround, doesn't always work with dashed lines)
(The way these things "should" be was taken from pg. 26 of Behind Bars)
