Why are any of these in screen coordinates?

Thanks, it's better to keep using the original coordinates. Reverted changes
against wm/default_window_resizer.cc and wm/window_resizer.*.

   if (bounds != details_.window->bounds()) {
     did_move_or_resize_ = true;
     details_.window->SetBounds(bounds);
