   2  *Notes: * t613  + tas5130A
   3  *      * Focus to light do not balance well as in win.
   4  *        Quality in win is not good, but its kinda better.
   5  *       * Fix some "extraneous bytes", most of apps will show the image anyway
   6  *       * Gamma table, is there, but its really doing something?
   7  *       * 7~8 Fps, its ok, max on win its 10.
