switch on the op passed in, not the active op. Gives us the right cursor

Browse Source 
2002-02-24  Havoc Pennington  <hp@pobox.com>

	* src/display.c (xcursor_for_op): switch on the op passed in, not
	the active op. Gives us the right cursor during resizing, etc.

	* src/errors.c: rearrange all the error stuff to adapt to the GDK
	change a while back, so now we print our X errors again

	* src/display.c (meta_display_begin_grab_op): remove KeyPressMask
	and KeyReleaseMask from the XGrabPointer(), this caused BadValue
	and kept the grab from ever succeeding. Fixes the problem with the
	GTK resize grip - this is why you shouldn't break your X error
	spew. ;-)

	* src/display.c: debug spew tweaks

	* src/window.c (meta_window_client_message): do some
	s/verbose/topic/ stuff
