Xfce non-mandrake galaxy theme?

[Alexander Toresson]

I installed Xfce 4.2.0 from os-cillation.de. The default wm theme I got was galaxy.
And no, it ain't mandrake galaxy - I've got that one too. The only difference
between the names is that mandrake galaxy has got a capital G in the wm theme listing.
galaxy (with small g) looks like a variation of Default-4.0, however, it uses the
new png feature of the wm themes, to create a kind of gradient on the windows caption.

This is my favourite theme, and I would like to modify it. However, I can't
find it on my hd. Neither "find / -iname galaxy" nor "find / -iname themerc" finds
it. It's not in /usr/share/themes, however, Galaxy (with capital G) is there.

Could anyone shed any light on this?
