gtk/gdk/win32/gdkinput-win32.c
Tor Lillqvist fcbf646cce Remove. (gdk_device_get_type): Drop class init function. The X11 version 
2007-02-19  Tor Lillqvist  <tml@novell.com>

	* gdk/win32/gdkinput.c
	(gdk_device_finalize, gdk_device_class_init): Remove.
	(gdk_device_get_type): Drop class init function. The X11 version
	doesn't have one either.
	(gdk_devices_list): Call gdk_display_list_devices() on _gdk_display.
	(gdk_display_list_devices): Check that the argument is
	_gdk_display.

	* gdk/win32/gdkinput-win32.h (GdkAxisInfo, GdkDevicePrivate):
	Cleanup: remove unused fields.
	* gdk/win32/gdkinput-win32.c: Corresponding changes. Fix function
	names in a few debugging printouts.
