tuns out that this isn't necessary. reverted.

   // trigger maximize mode at some point in the future.
   // The --enable-touch-view-testing switch can also mean that we may enter
   // maximize mode.
   // TODO(mgiuca): This can result in false positives, as it returns true for
   // any device with an accelerometer. Have TouchView-enabled devices explicitly
   // set a flag, and change this implementation to simply return true iff the
   // flag is present (http://crbug.com/457445).
