Owen Taylor 09d7eafb15 Switch set_cairo_target() virtual function to ref_cairo_surface()
2005-03-15  Owen Taylor  <otaylor@redhat.com>

	* gdk/gdkdrawable.h gdk/gdkdraw.c gdk/gdkpixmap.c gdk/gdkwindow.c
	gdk/x11/gdkdrawable-x11.c gdk/x11/gdkpixmap-x11.c gdk/x11/gdkwindow-x11.c
	gdk/gdkinternals.h: Switch set_cairo_target() virtual function to
	ref_cairo_surface()

	* gdk/gdkdrawable.h gdk/gdkdraw.h: Switch set_cairo_target() virtual
	function to create_cairo_context()

	* gdk/gdkwindow.c: Clear double buffer pixmaps with Cairo.

	* gdk/x11/gdkwindow-x11.c: Keep all components in GdkWindowObject.bg_color,
	not just the pixel.

	* tests/testcairo.c: Update for create_cairo_context()

	* gdk/gdkdraw.c (gdk_draw_trapezoids, gdk_draw_glyphs[_transformed]):
	Reimplement in terms of Cairo, bypass the vtable entries.

	* gdk/x11/gdkdrawable-x11.[ch] gdk/x11/gdkdisplay-x11.[ch]
	gdk/x11/gdkgc-x11.c gdk/x11/gdkpango-x11.c
	gdk/x11/gdkprivate-x11.h gdk/x11/Makefile.am: Remove
	implementation of draw_trapezoids / draw_glyphs[_transformed].

	* gdk/gdkpango.c: Switch GdkPangoRenderer to use Cairo

	* gdk/gdkpango.c gdk/x11/gdkpango-x11.c: Move
	gdk_pango_context_get_for_screen() into the backend independent code.

	* gdk/x11/gdkdrawable-x11.[ch]: Remove Xft use, use RENDER directly
	for drawing images.

	* gdk/gdkdrawable.h gdk/x11/gdkdrawable-x11.c: Remove
	gdk_draw_rectangle_alpha_libgtk_only.

	* gdk/gdkpixbuf.h gdk/gdkpixbuf-render.c: Add
	gdk_pixbuf_set_as_cairo_source()

	* gdk/gdk.symbols: Update

	* gtk/gtkcolorsel.c gtk/gtkhsv.c gtk/gtkiconview.c gtk/gtkruler.[ch]
	gtk/gtk[hv]ruler.c: Convert to Cairo rendering.

	* gtk/gtkstyle.c (gtk_default_draw_check, gtk_default_draw_focus,
	gtk_default_draw_option): Switch to Cairo. Simplify the checkbutton,
	radio button style for now to get something more scalable.

	*  gtk/gtksettings.c: #if 0 out the code to use PangoXft for hinting/
	antialiasing/dpi settings.
