//                                   EVERYTHING RUNS MORE SLOWLY IN WINDOWS 7
//
//   This application automatically expands to the size of the display:
//      Form1->AutoSize = NOT false;
//      Form1->BorderStyle = bsNone;
//      Form1 and PaintBox1 sizes are set to MonitorHeight and MonitorWidth.
//
//   Since the standard Windows controls do not appear:
//      Event handlers must be created to execute Form1->Close().
//      A PopUp Menu is used to show and hide the controls.
//
//   To make the application run with continuously varying parameters:
//      Nine timers control the positions of ten TrackBars.
//      The suspect population timer has been disabled.*
