BUG: TableView's setMouseTransparent method does not make mouse transparent

[Kevin Rushforth]

JavaFX does not use exclusive full-screen mode. It simulates full screen 
by using an undecorated window that is exactly the size of the screen. 
This means that pop-ups, such as those used by ComboBox and content 
menus, will continue to work (they use separate windows).
