CHanging key.size, accidental.size and stem.size in gregorianMusic

[Ali Cuota]

Hello,

I use these settings now, since this fits in the whole book (using
\include's and a mix of gregorian and western-traditional-notation).

But the size of Keys, accidentals and stems doesnt fit, and I dont
find how to override these...

(also #(layout-set-staff-size xx) doesnt have any effect)

Thanks in advance,

Franck
