Remove the clipboard viewer code. It didn't really do anything useful, and
2005-10-14 Tor Lillqvist <tml@novell.com> * gdk/win32/gdkdisplay-win32.c: Remove the clipboard viewer code. It didn't really do anything useful, and was just confusing and incomplete. Comments claimed we don't do delayed rendering, but in fact we do, for images. (The delayed rendering code has other problems, though, see #168173.) The clipboard viewer code was probably even buggy (the WM_CHANGECBCHAIN handled didn't propagate the message when necessary). It was just test code, it said so in a comment. Add something similar back later if necessary. (_win32_on_clipboard_change, _gdk_win32_register_clipboard_notification): Remove. (gdk_display_supports_selection_notification, gdk_display_request_selection_notification): Always just return FALSE. We didn't generate any GDK_OWNER_CHANGE events anywhere.
