now, this topic evolves faster than I can download mails via DSL....

The X client can deny being resized/repositioned by a window manager.

        attri.override_redirect=True;           /* keep uwm silent */
        attri.backing_store=Always;             /* offscreen saved pixels */
        attri.event_mask=ButtonPressMask;
        
XChangeWindowAttributes(display,WID,CWEventMask|CWOverrideRedirect|CWBackingStore,&attri);

that piece of C is somewhat dated, but the  override_redirect  flag 
still lives in recent X, I bet. However, I might not be very up-to-date 
with my bare-metal X hacking.

Anyway- the main idea would be that the X client (rvu) has _some_ wish 
how large and where it wants to be. That much the client may specify and 
maybe (like) even enforce by the attributes, thereby ignoring any window 
manager.
At last, the window manager is just another X-client in the world of X, 
- no super natural powers assigned to it.

PS: at least these bits belong on the dev list, mea culpa to those not 
used to an X-programming overdose...
