Drop gdk-pixbuf-xlibdrop-x11

The separate gdk-pixbuf-xlib API and shared library has been deprecated
for years, and is not even built by default; it has been moved out of
tree, into its own repository, in case people still depend on it.

- * @Short_description: Getting parts of an X drawable's image data into a pixbuf.
- * @Title: X Drawables to Pixbufs
- * 
- * The functions in this section allow you to take the image data
- * from an X drawable and dump it into a #GdkPixbuf.  This can be
- * used for screenshots and other special effects.  Note that these
- * operations can be expensive, since the image data has to be
- * transferred from the X server to the client program and converted.
- * 
- * 
- * These functions are analogous to those for the GDK version of
- * &gdk-pixbuf;.

- * gdk_pixbuf_xlib_get_from_drawable:

- * @src: Source drawable.
- * @cmap: A colormap if @src is a pixmap.  If it is a window, this argument will
- * be ignored.
- * @visual: A visual if @src is a pixmap.  If it is a window, this argument will
- * be ignored.
- * @src_x: Source X coordinate within drawable.
- * @src_y: Source Y coordinate within drawable.
- * @dest_x: Destination X coordinate in pixbuf, or 0 if @dest is NULL.
- * @dest_y: Destination Y coordinate in pixbuf, or 0 if @dest is NULL.
- * @width: Width in pixels of region to get.
- * @height: Height in pixels of region to get.
- *
- * Transfers image data from a Gdk drawable and converts it to an RGB(A)
- * representation inside a GdkPixbuf.
- *
- * If the drawable @src is a pixmap, then a suitable colormap must be specified,
- * since pixmaps are just blocks of pixel data without an associated colormap.
- * If the drawable is a window, the @cmap argument will be ignored and the
- * window's own colormap will be used instead.
- *
- * If the specified destination pixbuf @dest is #NULL, then this function will
- * create an RGB pixbuf with 8 bits per channel and no alpha, with the same size
- * specified by the @width and @height arguments.  In this case, the @dest_x and
- * @dest_y arguments must be specified as 0, otherwise the function will return
- * #NULL.  If the specified destination pixbuf is not NULL and it contains alpha
- * information, then the filled pixels will be set to full opacity.
- *
- * If the specified drawable is a pixmap, then the requested source rectangle
- * must be completely contained within the pixmap, otherwise the function will
- * return #NULL.
- *
- * If the specified drawable is a window, then it must be viewable, i.e. all of
- * its ancestors up to the root window must be mapped.  Also, the specified
- * source rectangle must be completely contained within the window and within
- * the screen.  If regions of the window are obscured by noninferior windows, the
- * contents of those regions are undefined.  The contents of regions obscured by
- * inferior windows of a different depth than that of the source window will also
- * be undefined.
- *
- * Return value: The same pixbuf as @dest if it was non-NULL, or a newly-created
- * pixbuf with a reference count of 1 if no destination pixbuf was specified; in
- * the latter case, NULL will be returned if not enough memory could be
- * allocated for the pixbuf to be created.
