Yes. That's my rule #1, and I am absolutely for implementing it.

Regardless of this, it still would be nice to see automatic cursor  
updates, too, since 10 fps is rather slow for mouse cursor updates.  
No full update is necessary for that, of course. But I fully  
understand that it might be difficult to implement for some backends,  
so I certainly don't insist on implementing that :-).
