Important! This is a callback method used by X#.
Normally, it should not be called in your application code.

This is one of the most important event handlers.
A window requires repainting when the window:
- Is partially uncovered by another window
- Is first shown
- Increases in size
- Is being restored after being iconized
- The window should retain enough information to redraw the screen as it was (or as it should be).
An ExposeEvent is also triggered by calling Repaint() or Update(); you should not call Repaint() or Update() during the Expose().
