Don't create a new graphics device on exit in ggsave(). Closes #2363.

Don't create a new graphics device on exist in ggsave(). This should address the remaining issue in #2363 and likely also the issue observed in #2752.

Look good to me!

I am writing a package in R that reads some files and reports variable statistics as table and various charts.
since I upgraded to ggplot2 version 3.0.0 I encountered two problems and reported it here. I think it is related to this issue but I am not absolutely sure:

1. ggsave() opens an inactive graphic device which is very confusing for the users.
2. ggsave() creates an error if the package is run in parallel. the error is:

a forked child should not open a graphics device

none of the above occurs on ggplot2 version 2.2.1. and the problem is solved if I downgrade.
I've tested on R 3.4 and R 3.5.
could you help me figure these out?

Can you please install the github version of ggplot2 and test whether this resolves the issues.

I installed and both problems are solved.

packageVersion('ggplot2')
