In Monocle, a MouseEvent with type MOUSE_ENTERED is never delivered.
The reason for this is that
`com.sun.glass.ui.monocle.MouseInput .setState()` will compare the old and the new window, and in case those are different a MOUSE_ENTERED event might be generated.
The calculations for getting the window based on the state will always return the same instance though.
Some functionality (e.g. Scene.setCursor()) depends on a MOUSE_ENTERED to be received at least once.
