Good! :)

It would be interesting to also test individual lib effects (although
that might give misleading results), for example using newer pango
with 2.6 and so on (as far as the compatibility goes). That wouldn't
neccessarilary give any worthwhile information about where to head
next, but it could be interesting to see how we've gotten here...

By *unsetting* the theme :)

Setting GTK2_RC_FILES to empty and making sure no
<SYSCONFDIR>gtk-2.0/gtkrc or ~/.gtkrc-2.0 is found should do the
trick.

That said, I guess the builtin theme is basically "just another gtk
theme" and benchmarking it may be a little silly since nobody actually
uses it... :)

I think I will look into plotting these into the same chart with the
gtkperf results to see how they differ... That should be interesting.
