I think it might be cleaner to implement convenience functions for this within
accessibility:

* It eliminates the need to include core/frame/Settings.h from more files, which
will hopefully save some recompiles
* It makes negating the test easier and more readable

Either move it back to AXObjectCache, or maybe implement it as a protected
method in AXObject.

Good idea, done.

             return false;
     default:
         return true;
