It seems like the best workaround here could come from RStudio. They
could provide a way for a user to indicate that they sometimes don't
want to use the RStudio graphics device (e.g. an option setting), and
your package could set and restore this option around your dev.new() call.
The other seems to be for your package to temporarily set
R_DEFAULT_DEVICE if the user doesn't already have it set, and use
noRStudioGD=TRUE. The disadvantage of this is that you need to do all
the platform-based decision making.
