nits: "Sets a property on the host window using platform-specific means."

if you plan to store something other than ints later, SetHostWindowIntProperty()
or SetIntPropertyOnHostWindow() may be better (or perhaps it'd be better to just
store strings to begin with)

I have no plan to add other than ints, but agree that it's better
to include int for clarify. Done.
