rebuild a png without doc-clean?

[Mark Polesky]

In my git repo, I compiled a commit that modified
Documentation/included/font-table.ly, which should have
updated two png files in NR A.6 "The Feta Font", but it
didn't.  I tried...

touch Documentation/notation.tely
touch Documentation/included/font-table.ly

...but still the png's weren't rebuilt.  Then I tried
removing the relevant png's:

rm out-www/offline-root/Documentation/b4/lily-258f09a7.png
rm out-www/offline-root/Documentation/a5/lily-5845f597.png

Still no luck.  They were rebuilt but without the change
that I expected.  Is there a way to trigger individual images
to rebuild without running doc-clean?  I attached the patch
in question just in case the problem is with my commit.

The problem I'm trying to fix:

In NR A.6 "The Feta Font", the "noteheads.sM1double" glyph
currently appears in the "Shape-note Notehead glyphs"
section, and should instead be listed in the "Default
Notehead glyphs" section.

Thanks.
