        - changed basic DOM mutation calls to assert that "this"
          is not floating, then added more uses of RefPtr to prevent the
          assertion from firing (at least during my testing and layout tests)

        - removed use of PassRefPtr as the type of a local variable; after talking
          with Maciej and Eric, this type of use is now "deprecated"
