 208                                   This property controls the anti-aliasing level used to improve
 209                                   graphic quality.
 210                                   If the property is set to "off", anti-aliasing is disable.
 211                                   To enable anti-aliasing, the property must set to either
 212                                   "2x", "4x", "8x" or "16x". In this case, it stands for the
 213                                   anti-aliasing level.
 214                                   For example, "16x" is a higher quality level than "2x".
 215                                   Specifying a higher anti-aliasing level improves image quality
 216                                   but also decreases graphic performances.
