I am wondering if we really need a views tooltip manager. (Perhaps in a separate
CL) We can rename TMV to TMAura and remove it from everywhere else.

Indeed. Right now, apart from aura, only TOUCH_UI uses the TMV. Once touch-ui
switches to aura, we can rename this.

+  TooltipManagerViews* tooltip_manager =
+      static_cast<TooltipManagerViews*>(GetTooltipManager());

Same comment about changing type of field to avoid cast.

This is complicated here since NWViews doesn't actually create a TMViews. NWGtk
creates it instead, and NWV just uses it. Since this is code going away pretty
soon, this is probably OK? :)

+  if (tooltip_manager)
+    tooltip_manager->UpdateForMouseEvent(event);
+#endif
   return HandleWindowOperation(event) ? true : delegate_->OnMouseEvent(event);
 }
