message: Flesh out the public functions which can be used for an OutputDevice in LuminaRandR.
  There is now:
  enable(QRect)
  changeResolution(QSize)
  move(QPoint)
  setGeometry(QRect)
  All of these run the same inline/backend function for turning on and configuring the monitor
diff: int main(int argc, char** argv){
  QString toggle = "HDMI-2";
  - QRect toggleGeom(0,0, 1600,900);
  + QRect toggleGeom(1980,0, 1600,900);
  int toggleOK = -1; //-1: automatic, 0: enable monitor, 1: disable monitor
  QApplication A(argc, argv);
