Hi Kieren, Hi Carl,
I don't think that a standard scaling will help in this case.
Here's an illustration of what could happened :
\markup {
\combine
\with-color #magenta
\scale #'(1.2 . 1.2)
\musicglyph #"clefs.G"
\musicglyph #"clefs.G"
}
Whatever glyph re-centering, you'll never get a proper whiteout.
One has to define a specific scaling function that can "blows" the glyph in
order to get a bold one.
Cheers,
Pierre
