I think we (the developers) are lucky here because Gdk/Gtk doesn't seem to 
have scaling functions!? Hm, seriously, I don't know. I can't seem to find 
anything about scaling in the GdkRGB or the different Pixbuf, Bitmaps and 
Image classes. Gtk has so called icon factories which contain one icon in 
different sizes, in case that's what you're looking for.

a) You need to be able to run ./configure without any warning. On FreeBSD 
you need to say --with-catalog=/usr/local/share/xml/catalog and the rest 
is guessed automatically. Then do a "make" in doc. This will leave two 
subdirectories...
b) with the same crap documentation which hangs off my website. So yes, 
the documentation still looks that bad.

We should (and hopefully will) have some documentation about this in our 
own docs.
containerAdd : use for all containers that can only have on child (i.e. 
are not derived from Box)
boxPackStart,...: for Boxes. grep the sources for "Packing" to find out 
more about this parameter. Unfortunately I haven't managed to produce any 
documentation about the data types.

Hope this helps,
Axel.
