18 *Notes: * t613 + tas5130A
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.
