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