* gtk/gtkviewport.c: corrects a small resize bug in the
viewport widget. The viewport widget provides a _set_shadow
function to draw its shadows. But if GTK_SHADOW_NONE is sent
to this function, the viewport isn't resized correctly (it's
still considered as a shadowed widget). (gtk-fortier-971213-0)
* gtk/gtknotebook.c: this patch fixes the redraw problems of
notebook tabs, without using gdk_gc_set_clip_rectangle.
(gtk-hamann_jeske-971218-0)
* add gtk_widget_(show/hide)_all (Stefan Wille)
(gtk-wille-301297-0) Patch for testgtk not included
because it did not patch clean.
