The trouble is that the packer really isn't different from GtkHBox and
GtkVBox - the only useful packing layouts are horizontal or vertical

And in general, it doens't make sense to have multiple widgets to do
the same thing. People want to be told what to use in a clear
fashion. We need to have consistent recommendations.  Not "we usually
use Gtk[HV]Box, but if you want, you could use GtkPacker instead. It
does about the same thing".

(AFAIK, the only really things that are more powerful about the packer
in practice are the internal and external padding; and external
padding is handled in GTK+ with GtkAlignment.)
