[gtk+/rendering-cleanup: 125/140] API: Remove drawable getters for visual, screen and depth

[Benjamin Otte <otte src gnome org>]

commit 47290e95e6b0a29120a52766de0d29be46156558
Author: Benjamin Otte <otte redhat com>
Date:   Sun Aug 29 01:49:30 2010 +0200

    API: Remove drawable getters for visual, screen and depth
    
    Removed and replaced are:
    gdk_drawable_get_visual() => gdk_window_get_visual()
    gdk_drawable_get_screen() => gdk_window_get_screen()
    gdk_drawable_get_depth()  => gdk_visual_get_depth
                                              (gdk_window_get_visual())
