19  *      * Focus to light do not balance well as in win.
20  *        Quality in win is not good, but its kinda better.
21  *       * Fix some "extraneous bytes", most of apps will show the image anyway
22  *       * Gamma table, is there, but its really doing something?
23  *       * 7~8 Fps, its ok, max on win its 10.
