I think this is a valuable feature but I'd prefer to not add another 
-sdl-<feature> option.  In fact, I'd like to get rid of the existing ones.

I'd suggest that you look at introducing a new -display option.  The 
syntax would look like this:

-display sdl,frame=off,scaling=off
-display vnc,address=:3,tls

If you use the recently introduced QemuOptions framework, it should be 
very straight forward.  I would accept an initial patch that just 
converted sdl as vnc is a bit more difficult.

The advantages of this approach are numerous beyond just aesthetics.  
This would allow these display properties to be manipulated via the -set 
option which means that eventually, they'll be tunable via a host 
configuration file.  It also puts together some interfaces for 
supporting multiple graphics cards for guests and multiple display backends.
