Thanks!

I also think they are too big.  The question is, how should we achieve
that?  Is there something like
"musical-glyphs-font-size-when-used-in-markups"?  Or should we simply
make new glyphs smaller (i somehow don't like this)?

Yes, approximately.

I can try this.
The attachments i'm sending currently are results of playing with
image editor, actually.  I will make new glyphs when the code that
uses them will be ready.

Maybe, but i'd prefer to avoid this if possible for the sake of simplicity.

I think we have to answer a general question: how (technically)
aligning accidentals should work.  Currently it seems a royal mess - i
haven't investigated source yet, but look at this snippet

\markup { \flat \sharp \natural \large "blah"  }
\figures { <6>16 <_-> <_!> <_+> <4> }
\figures { <6-> <6!> <5+> }
\chords { fis es }
\new ChordNames { \germanChords \chordmode { fis es } }

in each line accidentals are aligned in a different way.  This sucks.

There are two different ways we would like to align accidentals (see
attachment 1; notice that relative aligning of flat and sharp is
different).  I think these two ways would be enough for all uses.  How
do we want to implement them?  The first method (for use with text)
should be implemented by moving the baseline of the glyphs, i think.
For the second method, i see two possibilities:
- use bounding box (adjusted a bit), i.e. the bottom of bounding box
becomes baseline (i hope its possible?); see attachment 2,
- vertically center the accidental on parent grob.  This will give
different results in case of differently sized grobs (see attachment
3).  There can also be a problem when there is no parent grob, for
example in figured bass.

What do you think?
