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.

| 3 * This is the demo program for the animated menu. We will use to test the MBAF API. | |
| 4 * We need to have group item1-item9 in the SVG file. Initially, we will show | |
| 5 * item1-item8 only. When a up/down key is pressed, we will draw the next item in item9 and | |
| 6 * add two words to move item1-item9 smoothly. The first word move items to the 3/4 position | |
| 7 * fastly. The second will move it from 3/4 to the final position slowly to make retard effect. | |
| 8 * | |
| 9 * If we press another key before the second words finish, we will delete the word and replace | |
| 10 * it with a word to move it fastly to the final position and then we will repeat the procedure | |
| 11 * to add another two words to move it to the next position. | |
