/**
* gdk_pixbuf_xlib_render_pixmap_and_mask:
* @pixbuf: A pixbuf.
* @pixmap_return: Return value for the created pixmap.
* @mask_return: Return value for the created mask.
* @alpha_threshold: Threshold value for opacity values.
*
* Creates a pixmap and a mask bitmap which are returned in the @pixmap_return
* and @mask_return arguments, respectively, and renders a pixbuf and its
* corresponding tresholded alpha mask to them. This is merely a convenience
* function; applications that need to render pixbufs with dither offsets or to
* given drawables should use gdk_pixbuf_xlib_render_to_drawable_alpha() or
* gdk_pixbuf_xlib_render_to_drawable(), and
* gdk_pixbuf_xlib_render_threshold_alpha().
*
* If the pixbuf does not have an alpha channel, then *@mask_return will be set
* to None.
