BugOpts DisplayNewWindowNames

Note that a window's class cannot be changed once the window is
mapped; only in the WithDrawn state.  I've mentioned this a few times
before on this list; only one or two GTK apps that I know of decide to
change their title after the window has been mapped; transitioning
from FVWM's default of "NoName" to something else -- but that won't be
what's happening with XZoom.

The third one is that style line ordering matters a great deal in the
config file.
