it turned out it was _much_ harder then expected.

I ended up writing a second engraver which sets the new defined
grob-property "TabNoteHead.bend-me", which decides whether a string is

To get there, I used the context-property `noteToFretFunction'. Using
it in the engraver leads to the need to give it the appropiate
Disadvantage: Actually `noteToFretFunction' is now used twice, in my
BendMeEngraver _and_ in the default Tab_note_heads_engraver.
If someone knows a better method please shout!

Nevertheless, it's now 4 times faster than before.

Ofcourse, still a lot on the TODO-list...

The current state attached in a tarball.
