While we are at X11 and Wayland - are there any other aspects of R which
would need to be rewritten or adapted? I guess, a new graphic device
might be necessary?
It might be an important exercise to find this out as it will be
relevant for all the Ubuntu users in the medium future (probably earlier?)
I send this to the r-sig-debian as well, as it might be more relevant where.
