Sets the event mask for a given device (Normally a floating device, not
attached to any visible pointer) to @window. For example, an event mask
including #GDK_BUTTON_PRESS_MASK means the window should report button
press events. The event mask is the bitwise OR of values from the
#GdkEventMask enumeration.
