[Rd] interactive graphics devices

I probably missed this discussion, but why not just ASK the device if
it is interactive? I can easily imagine a case where a device might be
interactive or not depending on how it was started. In fact, I don't
have to imagine a case since the Quartz device in R-devel can have
exactly this behavior. Something like a Cairo device might also have
this behavior, though I don't know if the current Cairo devices
support it.
