You may want to look at the tutorial, if you haven't found it already:

The pixmap path was only implemented to allow the tiled pixmaps specified
in the gtkrc to be found.  It's not carried into the application,
although, it's an interesting idea..  What do others think ?  Should the
gdk pixmap loading functions search the pixmap path ?

Mmm.. yeah.  It was a bit of a hack I admit :)

Hmm.. OK, I'll look at it later (I'm at work right now) just to see what I
was thinking, and see if it can be improved.
