[Rd] issues with dev.new avoiding RStudio plot device on unix?

Sorry, should have given more background.  x11 works fine on all my 
systems when called by x11().  I'm the maintainer of a package that uses 
the animation library, which has performance issues when used with the 
RStudio plot device.  But if you call plot.new() when using RStudio, you 
get an RStudio device, not the standard device for the platform because 
it overrides the device option.  So I've had to have the library do 
platform detection and platform-specific device calls, which R CMD check 
doesn't like.  I believe that noRStudioGD argument was avoided to give 
users a way around this, but it doesn't seem to be behaving correctly in 
the unix interactive case.
