use smaller filetree arrows

[DancemasterGlenn]

Here's the other issue I think is important to address:

within a filetree view (firefox bookmark sidebar, or the side panel of gconf-editor), themes like Ambiance have small, elegant triangle-shaped buttons, where dust has very large triangle buttons. I believe this is configured within the metacity-theme-1.xml file, but I'm not sure which value to change/add. I believe however it is changed, dust should be made to use Ambiance's tree icons (or at least smaller ones).

Now, because I don't know how they are coded in, I don't know if one of the themes in question is falling back on a default, or if both are hard-coded somehow, but (and I know this is totally personal opinion), Ambiance makes the smaller ones look more appropriate (especially when a person is using a smaller font). I'd fix this myself and just upload a patch, but I seriously can't figure out how they're coded in at all. Any help on this? It would be great to see this pushed into maverick before release, if that's even possible at this point.

I filed a bug for this on the gnome-themes-ubuntu page, hopefully this is helpful: https://bugs.launchpad.net/ubuntu/+source/gnome-themes-ubuntu/+bug/629981
