 * Most user interface commands are routed through this, to give us the
 * Undo/Redo mechanism. If you add more commands, such as changing the shape colour,
 * you will need to add members to 'remember' what the user applied (for 'Do') and what the
 * previous state was (for 'Undo').
 * You can have one member for each property to be changed. Assume we also have
 * a pointer member wxShape *shape, which is set to the shape being changed.
 * Let's assume we're changing the shape colour. Our member for this is shapeColour.
 *
 * - In 'Do':
 *   o Set a temporary variable 'temp' to the current colour for 'shape'.
 *   o Change the colour to the new colour.
 *   o Set shapeColour to the _old_ colour, 'temp'.
 * - In 'Undo':
 *   o Set a temporary variable 'temp' to the current colour for 'shape'.
 *   o Change the colour to shapeColour (the old colour).
 *   o Set shapeColour to 'temp'.
 *
 * So, as long as we have a pointer to the shape being changed,
 * we only need one member variable for each property.
 *
 * PROBLEM: when an Add shape command is redone, the 'shape' pointer changes.
 * Assume, as here, that we keep a pointer to the old shape so we reuse it
 * when we recreate.
