UNIX-mode on:

After unsuccessfully trying to find a way to access the tonic 
information from the stencil callback, I've finally realised that the 
contexts don't exist when the stencils are called. It therefore seems 
that I'm going to need to modify the engraver to set the scale-degree 
as an internal grob property.

To do this I'm going to have to set-up a dual boot, re-read all the 
git stuff and practice building and testing, so please shriek if I'm 
going down the wrong route :)
