Tue Jan 29 17:40:02 2002  Owen Taylor  <otaylor@redhat.com>

        * gdk/gdkpixbuf-render.c (gdk_pixbuf_render_to_drawable):
        Call _gdk_draw_pixbuf(), thus enabling using this function
        for pixbufs with alpha. (#68801)

        * gdk/gdkdraw.c (gdk_drawable_real_draw_pixbuf): Move
        implementation of gdk_pixbuf_render_to_drawable()
        to here.
