	* gdk/linux-fb/gdkinput-ps2.c (send_button_event):
	Do implicit button grabs, even if the window doesn't
	want the event.
	(gdk_fb_window_send_crossing_events): If there is a
	grab, only the grabbed window gets normal enter/leave
	notifications. On ungrab go from grabbed window to current.
	Don't send any notification to b when propagating from c -> b.
	If setting a grab on window, don't set prev_window.
	(handle_mouse_input): Send enter/leave events to the window the
	mouse is over, not the grabbed one.
