Individual staff sizes?

[Mats Bengtsson]

I tried to update input/test/staff-size.ly but don't
manage to set the staff-space separately for each 
staff.

When I do
\property Staff.StaffSymbol \override #'staff-space = #0.8
nothing happens. 
On the other hand, when I do 
\paper{
  \translator{\StaffContext
    StaffSymbol \override #'staff-space = #0.8
  }
}
the setting works, but that's of course unusuable since
all the staffs get the same size.

The example file also illustrates a clear disadvantage
of the new property setting mechanism.

The single line 
    \property Staff.fontSize = #-1
corresponds to:
 \property Staff.BarLine \override #'font-relative-size = #-1
 \property Staff.Clef \override #'font-relative-size = #-1
 \property Staff.SeparatingGroupSpanner \override #'font-relative-size = #-1
 \property Staff.SeparationItem \override #'font-relative-size = #-1
 \property Staff.StaffSymbol \override #'font-relative-size = #-1
 \property Staff.TimeSignature \override #'font-relative-size = #-1
 \property Staff.VerticalAxisGroup \override #'font-relative-size = #-1
 \property Thread.NoteHead \override #'font-relative-size = #-1
 \property Voice.Beam \override #'font-relative-size = #-1
 \property Voice.DynamicLineSpanner \override #'font-relative-size = #-1
 \property Voice.DynamicText \override #'font-relative-size = #-1
 \property Voice.NoteColumn \override #'font-relative-size = #-1
 \property Voice.Stem \override #'font-relative-size = #-1

I definitely hope you don't plan to remove the generic-property.scm
at least until there's an equivalently powerful replacement.
