[Lcdproc] Patch: MtxOrb adjustable backlight and display detection

[Markus Dolze]

Hi,

I have questions on how the Display On / Off and Set Brightness commands 
of Matrix Orbital displays work:

   1. If I use the 'Display Off' command, does it just turns the
      backlight off like for older versions or does it completely turns
      the display off?
   2. If the display's backlight is off, what happens if I issue a 'Set
      Brightness' command? Does the backlight stays off until a 'Display
      On' command is issued or does the backlight automatically turns on?
