Probably the better thing to do would be to provide them to Eeli, so
he can test them and then decide whether or not to include them with
the actual Subversion.  If, indeed, there are problems with the SVG
files, as has been indicated by Gary and yourself, then perhaps
running the png files in there would alleviate those warning messages
as well as give us rendering on Windows.  Of course, you could also
provide them to me and I will test them directly in Windows XP to see
if they correct the issue and report back on that.  If it works, even
if the SVG files are just fixed, then the installation procedure can
be changed so that it installs the PNG files in Windows instead of the
SVGs.
