Undecorated-interactive stage style

[Kevin Rushforth]

This looks interesting and useful. I'd like to hear from other 
developers as well.

A few comments:

1. We might want to consider whether there is a better name (nothing 
comes to mind at the moment)
2. This will almost certainly need to be a ConditionalFeature (since it 
might not be supportable on certain platforms, such as embedded platforms)
3. We will need an implementation on all three desktop platforms: 
Windows, macOS, Linux
4. You will need to add tests (at least manual if automated tests prove 
to be infeasible)
