Re: Use arbitrary notes (with stem/flag) as MMR stencil override

Hi David,

> What do you think the presence or absence of some interface implies?

I think the presence of an interface means a shared behaviour is implied 
between grob types which have that interface, the implementation of which is 
individually determined for each grob type. For example, I think that all grob 
types which share the text-interface have a baseline-skip property that can be 
interacted with (where hopefully an implementation of that property for that 
grob type has been created, or setting the property will have no effect).

So in my (possibly deeply flawed) grasp of how interfaces work: a 
measure-centred-interface might add a centre-in-measure property, which centres 
the grob [type] within the current measure; for MMRs that would be set to true 
by default, and for other grob types (e.g., NoteColumn or NoteHead) it might be 
set to false by default. Overriding that property would then engage whatever 
programming was in place to centre the grob.

How far off the mark am I?

Thanks,
Kieren.
