Implement better handling of Wintab tablet context overlap on Win32.

2005-02-24  Robert Ögren  <gtk@roboros.com>

	Implement better handling of Wintab tablet context overlap on
	Win32. (#167298)

	* gdk/win32/gdkinput-win32.c (_gdk_input_set_tablet_active): New
	function that brings any tablet contexts to the top of the overlap
	order.
	* gdk/win32/gdkinput-win32.h: Declare _gdk_input_set_tablet_active ()
	* gdk/win32/gdkevents-win32.c (gdk_event_translate):
	Call _gdk_input_set_tablet_active when a window is activated (on
	WM_ACTIVATE)
