GdkEventCrossing "is generated when the pointer enters or leaves a
window."

The field detail is a GdkNotifyType that shows "the kind of crossing
that happened (GDK_NOTIFY_INFERIOR, GDK_NOTIFY_ANCESTOR,
GDK_NOTIFY_VIRTUAL, GDK_NOTIFY_NONLINEAR or
GDK_NOTIFY_NONLINEAR_VIRTUAL)."

GDK_NOTIFY_INFERIOR means "the window is entered from an inferior or
left towards an inferior."
