  wayland: Implement IME support.
  
  Note that this is purely to make it possible to enter text that requires
  composition - for example, before this commit Kanji input didn't work at all.
  
  The big problem this still has is that we need the window position, and this is
  still not implemented. Once we have this information we can do the equivalent
  of XTranslateCoordinates to put the rectangle where we want it.
