New implementaion that more closely mimics the events that an X server

Browse Source 
2001-01-15  Tor Lillqvist  <tml@iki.fi>

	* gdk/win32/gdkevents-win32.c (synthesize_crossing_events): New
	implementaion that more closely mimics the events that an X server
	would generate. Especially, properly generate GDK_NOTIFY_VIRTUAL and
	GDK_NOTIFY_NONLINEAR_VIRTUAL crossing events. This makes buttons
	with nested preview widgets, for instance, more responsive when
	you move the mouse quickly into them.
	(find_window_for_pointer_event): Make it actually compile.
	(gdk_event_translate): Set send_event to the value of
	InSendMessage (). This doesn't really mean the same as X11's
	send_event flag, but is close enough, says jpe@archaeopteryx.com
