It's rather antisocial for an application to constantly raise itself
[e.g. by tracking VisibilityNotify events] so that it isn't overlapped -- 
imagine the conflict between two such programs running.  
	The only sure way to have your window appear on the top of the stack
is to make the window override-redirect; this means that you are temporarily
assuming window-management duties while the window is up, so you want to do 
this infrequently and then only for short periods of time (e.g. for popup 
menus or other short parameter-setting windows).
