   4 Subject: [PATCH] ivi-shell: transforming from a single screen coordinates to
   5  multi screen coordinates: global coordinates.
   6
   7 In single screen, the coordinates of layer local coordinates are the
   8 same as global coordinates. However, to support multi screens, the
   9 layer-local coordinates shall be transformed to multi screen coordinates,
  10 which is global coordinates. The abosolute coordinates of a screen in global
  11 stored in (x,y) of output of its weston output so it shall be used to
  12 transform layer-local to global coordinates.
