Fix the svg:use. For a svg:use, it is a group which include the content it reference. It means that we can not tween it to its origin object directly. Instead, we need to ungroup it and then use the result matrix to generate the tweened transformation matrix. Therefore, we need to concate its matrix to the referenced object. Ad center object when the bbox-x is not available.

/*! \page create_graph_engine Create a Graphic Engine.
 *
 * To create a graphic engine, you need to declare and define types
 * and functions that had been declared in
 * include/mb_graph_engine_cairo.h in a separated header an c file.
 * Likes what mb_graph_engine_skia.h does.
 *
 * You should also add options in configure.ac to enable the graphic
 * engine.  You also need to add lines in include/mb_config.h.in and
 * include/mb_graph_engine.h to include correct header for the graphic
 * engine enabled by the user.
