nit: Please arrange the forward declarations in the
alphabetical order. (Well, LocalFrame and LayoutRect
are not in the correct order, but I assume that's
just a mistake.)

Generally speaking, it is a bad idea to define a function
which has such a generic name in the namespace level scope.

I have several suggestions on naming:
* Please make sure the function returns a String describing
  the position, such as "nodePositionAsString".
* Please put "ForTesting" to the function name to make it
  clear that the function should only be used from tests.

Done.
