Actually, modifying your widget's colors is almost
always a bad idea, but it was such a common FAQ, that
we decided we should provide a function to do it
well, rather than having people do it in more complicated
ways and get it wrong.

You can do most of this stuff with gtk_rc_parse_string()
and the RC priority system if you really need
On rare occasions programmers *do* have legitimate reasons
for doing things that are in the domain of the theme.
So we allow it. But there isn't a big emphasis on
making it easy.

I'm not sure using XMMS as an example is a _positive_
argument :-). But in any case the main window of
XMMS is really only using GTK+ as an implementation

Consistency, consistency, consistency. Just because
the user may not care exactly how their progressbar
looks, doesn't meant they want it to look different
in every app.

Not exactly ... style properties are meant for themes,
and an app programmer has to go to some lengths to
