gtk_container_forall()

[Owen Taylor <otaylor redhat com>]

gtk_container_forall() is currently listed in the:

 /* Non-public methods */

Sections of gtkcontainer.h. I'm currently going through
gtkcontainer.h and _prefixing the non-public methods,
but I'm not sure that doing so for gtk_container_forall()
makes sense; 

 - There doesn't seem to be anything particularly,
   private about it, though must public cases will want
   gtk_container_foreach. Since we require containers to
   implement the ::forall signal, we can't say that this
   is some internal detail that nobody should ever see.

 - It is currently used in a handful of places external
   to GTK+. (http://cvs.gnome.org/lxr/ident?i=gtk_container_forall 
   gives some.) Many of these could probably use foreach()
   but I'm not sure _all_ could.

 - gtk_container_forall() might actually be useful for 
   things like gui builders, accessibility tools, 
   debugging tools, and the kind of bad hacks that every
   sufficiently complex app will eventualy need.
