Subject: Mac OS: the present code asks the system to build the mini window
 image when a subwindow-less window is miniaturized, and builds itself the
 image when a window with subwindow is miniaturized. That is mostly OK, but it
 fails when a window containing a subwindow is miniaturized (a mini image is
 computed), deminiaturized, the subwindow is removed or hidden, and the window
 is miniaturized again: the old mini image is used, and that is not
 appropriate. The solution is to remove the FLTK-computed mini image when a
 window with subwindow is deminiaturized.
