-// When the mouse is pressed over the size button or the size button is touched:
-// - The minimize and close buttons are set to snap left and snap right

-// - The size button stays pressed while the mouse is over the buttons to snap

-// When the drag terminates, the action for the button underneath the mouse
-// is executed. For the sake of simplicity, the size button is the event
