	* gdk/gdkpango.[ch]: Add GdkPangoRenderer, a subclass of
	PangoRenderer targeting GDK drawables. Use to implement the old
	gdk_draw_layout() and friends.

	* gdk/gdkdraw.c gdk/gdkdrawable.h gdk/gdkwindow.c gdk/gdkpixmap.c:
	Add gdk_draw_glyphs_transformed() gdk_draw_trapezoids() and
	the corresponding members of GdkDrawableClass. Add a fallback
	implementation of gdk_draw_trapezoids() in terms of pixbufs.

	* gdk/gdkwindowing.h gdk/x11/gdkg-x11.h: Add
	_gdk_windowing_gc_get_foreground() to enable the fallback
	trapezoid implementation.

	* gdk/x11/gdkdrawable-x11.c gdk/x11/gdkdisplay-x11.h: Implement
	draw_glyph_transformed,	draw_trapezoids.

	* gdk/x11/gdkdrawable-x11.[ch]: Add
	_gdk_x11_drawable_draw_xtrapezoids, _gdk_x11_drawable_draw_xft_glyphs
	for use of GdkX11Renderer.

	* gdk/x11/gdkgc-x11.c gdk/x11/gdkprivate-x11.h: Implement
	GDK_TILED, GDK_STIPPLED, GDK_OPAQUE_STIPPLED in the RENDER codepath.

	* gdk/gdkpango-x11.c: Add GdkX11Renderer... a subclass of
	PangoXftRenderer that does tiles/stipples and fallback rendering
	of trapezoids without the RENDER extension.

	* gdk/gdkpango-x11.c gdk/x11/gdkscreen-x11.[ch] _gdk_x11_renderer_get:
	Add _gdk_x11_renderer_get() to get a singleton GdkX11Renderer
	for the screen.

	* gdk/x11/gdkdrawable-x11.c (get_impl_drawable): Fix a None/NULL
	confusion.

	* gtk/gtklabel.[ch] gtk/gtk.symbols: Add gtk_label_set/get_angle(),
	and an ::angle property.

	* gtk/gtklabel.c: Remove #if 0'd dead code gtk_label_paint_word().

	* gtk/gtktextdisplay.c: Switch to using a GtkTextRenderer subclass
	of GdkPangoRenderer for drawing.

	* gtk/gtktextlayout.[ch] gtk/gtktextdisplay.c: Switch to using
	gtk_attr_shape_new_with_data() to store backreferences to
	embedded pixmaps and widgets. Leave line_display->shaped_objects
	around for backwords compatibility.

	* gdk/gdkpango.[ch] (gdk_pango_context_set_colormap): Describe
	as deprecated, remove implementation.

	* gtk/gtkwidget.c (gtk_widget_create_pango_context): Remove
	call to gdk_pango_context_set_colormap.

	* demos/gtk-demo/Makefile.am demos/gtk-demo/rotated_text.c: Add
	a demo showing drawing rotated text.

	* tests/testgtk.c: Add a rotated-label test, and also a rotated
	drawing test (differs from demos/gtk-demo/rotated_text by also
	using a tile)
