   3 Subject: ivi-shell: use primary screen for resolution values
   4
   5 Screen resolution values (width, height) are always grabbed
   6 from the first screen, n.0, which can be a bad choice if it
   7 is not the one really used as main display.
   8
   9 This mostly happens on hardware with a VGA adapter, such as
  10 laptops or Renesas R-Car E2 "Silk", and prevents correct
  11 layout stretching (black borders).
  12
  13 Discover the primary screen and use its values.
