Don't propagate mouse events to windows that want extended input events.

Browse Source 
2004-05-11  Robert Ögren  <gtk@roboros.com>

	* gdk/win32/gdkevents-win32.c (propagate): Don't propagate mouse
	events to windows that want extended input events. (#142943)
	(gdk_event_translate): Move check for extended input devices to
	propagate, new parameter to propagate.
	(gdk_pointer_grab, gdk_display_pointer_ungrab): Enable calls to
	_gdk_input_(un)grab_pointer. (#142943)

	* gdk/win32/gdkinput-win32.c (_gdk_input_other_event): Check for
	input grab. [Fix missing update of impl in "dijkstra" event
	propagation loop] Drop the parallel "impl" pointer, just use a
	cast. Don't propagate beyond windows that want normal input
	events. (#142943)
	(gdk_input_grab_pointer, gdk_input_ungrab_pointer): Limited
	implementation of input grab. (#142943)
