title: chrome detecting integer as NPVariantType_Double with npruntime plugin?
body: <p>I am trying to call a function through javascript via my NPRuntime plugin
  but when i pass an integer value to a function,chrome detects that as NPVariantType_Double while firefox is taking same as NPVariantType_Int32.
  Can we do avoid this without modifying script to make sure that both firefox and chrome detects it as NPVariantType_Int32.</p>
