mus should tell you this? i.e.: this code should never get invoked?

[sadrul, 2016/10/11 19:14:14]

There's a window_finder_mus.cc that should be used, yeah.

[tonikitoo, 2016/10/12 13:44:23]

Right. This  should never be invoked, but we need a stub implementation, to link
successfully. I will add a  NOTREACHED().

In case of other platforms, we have window_finder_{win,mac,x11,chromeos}.cc
implementing ::GetLocalProcessWindowAtPoint.
 
In practice, when --mash is passed, WindowFinderMus takes place.

     const gfx::Point& screen_point,
     const std::set<gfx::NativeWindow>& ignore) {
-  return GetLocalProcessWindowAtPointAsh(screen_point, ignore);
+  NOTIMPLEMENTED();
+  return nullptr;
 }
