I now come up with the attached code.

It's now possible to preserve the default glissandi. Also,
"glissando-stubs" are printable.

Still not sure if it's suitable for our docs.
Apart from the user-interface, which is still terrible, a new
context-property is defined and used: fingerSlide (boolean)

Cheers,
