Havoc Pennington 4d48b106f0 use gdk_cursor_unref instead of destroy 
2000-01-30  Havoc Pennington  <hp@pobox.com>

	* gtk/testgtk.c (set_cursor): use gdk_cursor_unref instead of
		destroy

			* gdk/gdkimage.c (gdk_image_ref): image wasn't being returned

				* gdk/gdkprivate.h: declare
_gdk_cursor_destroy which is then
	implemented in platform-specific code

		* gdk/Makefile.am (gdk_c_sources): add gdkcursor.c

			* gdk/x11/gdkcursor-x11.c (gdk_cursor_destroy):
rename with an
	underscore in front

		* gdk/win32/gdkcursor-win32.c (gdk_cursor_destroy):
			put an underscore in front

				* gdk/gdkcursor.c: new file, implements
					gdk_cursor_ref/gdk_cursor_unref

						* gdk/gdkcursor.h: Refcount GdkCursor

							* gdk/gdkcompat.h
(gdk_cursor_destroy): compat
