        * gtk/gtktextlayout.[ch], gtk/gtktextdisplay.c: Use new
	PangoAttrShape to reserve space for pixmaps, add
	GSList *pixmaps to GtkTextLineDisplay, draw the pixmaps
	in the display functions.

	* gtk/testgtk.c (create_layout): Set some more exotic
	scrolled window options

	* gtk/gtkscrolledwindow.[ch] (gtk_scrolled_window_set_shadow_type):
	Add function to set the shadow type of a window, to allow
	putting a shadow around widgets such as GtkLayout or GnomeCanvas
	which don't draw their own frame.
