Avoid spurious core pointer events when the tablet pen is lifted.

2005-07-28  Robert Ögren  <gtk@roboros.com>

	Avoid spurious core pointer events when the tablet pen is lifted.
	(#167000)

	* gdk/win32/gdkinput-win32.c (set_ignore_core): New static function,
	handles delayed unsetting of _gdk_input_ignore_core.
	(_gdk_input_other_event): Call set_ignore_core instead of setting
	_gdk_input_ignore_core directly.
