Screen default queryStackingOrder collect: [:h | DisplaySurface findRegistrant: h]
lists the windows on the screen from bottom to top. So if
myWindow == DisplaySurface findRegistrant: Screen default queryStackingOrder last
is true then myWindow is not behind another window. But since there can be more than one
window that is not covered by other windows, this expression can be false even if
myWindow is completely visible. You need to compare its position with the position of all windows
"above" it to check that it is not hidden by these windows.
