[gtk-vnc-devel] [PATCH] Add interface to force pointer grab

[Anthony Liguori <anthony codemonkey ws>]

I'll commit push this to outgoing tomorrow if there are no objections.  
I've updated the full screen mode in gvncviewer to use it too.  I think 
this is what we're looking for semantically.

Regards,

Anthony Liguori
