The event minimize occurs when the image of a window is removed from the display (typically an icon will remain at the bottom of the display).
Note: this event means that the window may or may not change size, and that it may or may not be needed to execute "action logic" similar to the logic for the event resize (see also the events maximize and restore).
In MWAPI, this event is called "MIN".
