	* configure.in (GDK_PIXBUF_DIR): make the symlink.  Does not work
	for srcdir != buildir != .  Beats me why; I can't figure it out.
	AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.

* gdk_pixbuf_new_from_data:

* @has_alpha: Whether the data has an opacity channel.
* @width: Width of the image in pixels.
* @height: Height of the image in pixels.
* @rowstride: Distance in bytes between rows.

* Creates a new #GdkPixbuf out of in-memory RGB data.
