docs: Sets an offset in a larger frustum. This is useful for multi-window or
  multi-monitor/multi-machine setups.
  
  For example, if you have 3x2 monitors and each monitor is 1920x1080 and
  the monitors are in grid like this
  
  +---+---+---+
  | A | B | C |
  +---+---+---+
  | D | E | F |
  +---+---+---+
  
  then for each monitor you would call it like this
  
  var w = 1920;
  var h = 1080;
  var fullWidth = w * 3;
  var fullHeight = h * 2;
  
  --A--
  camera.setOffset( fullWidth, fullHeight, w * 0, h * 0, w, h );
  --B--
  camera.setOffset( fullWidth, fullHeight, w * 1, h * 0, w, h );
  --C--
  camera.setOffset( fullWidth, fullHeight, w * 2, h * 0, w, h );
  --D--
  camera.setOffset( fullWidth, fullHeight, w * 0, h * 1, w, h );
  --E--
  camera.setOffset( fullWidth, fullHeight, w * 1, h * 1, w, h );
  --F--
  camera.setOffset( fullWidth, fullHeight, w * 2, h * 1, w, h );
  
  Note there is no reason monitors have to be the same size or in a grid.
