Comment:

 I have uploaded a new patch for review.

 This patch use the deprecated gdk-keyboard-grab, gdk-pointer-grab. Now I
 see it working, if we want, we can try use the new api.

 Is not clear for me, why we need grab the mouse.

 Another strange issue (may be a bug a lower levels) is after testing a
 lot, I can see cases where the mask returned by window.get_pointer() is 0,
 then the keyboard and mouse are not ungrabed. I have modified the
 condition to ungrab in that situation too.
