* 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. -Shawn
