Glissando tab layout and style minTieLength
It appears that the default glissando layout size is related to style::minTieLength. It looks like minTieLength*2
If you increase the style::minTieLength from 1 to 2, the gliss stretch out way too much. They shouldn't stretch out at all.
Need to rethink gliss layout and maybe use minTieLength+n instead of minTieLength*2.
Even better, use a style called minGlissLength
