I can reproduce the font-naming issues, but I can't reproduce the
`off-by-15' issue.  I made a very simple LY file, generated SVG from
that, and double-checked all of the hexadecimal values.

Also to be completely accurate here, the hexadecimal values are *four*
digits.  For example, the G-clef has a hex value of e1a7.

Here are the workarounds for Inkscape 0.46 that I am using:

1) Move all of LilyPond's OTF fonts into ~/.fonts
2) Change all instances of `currentColor' to `#000' in the SVG file.
Apparently this is no longer an issue with latest Inkscape SVN.

After ungrouping everything, I can use the SVG file just fine.
