What is FVWM’s future with Wayland coming online? Is it fully compatible/compliant?
In order to do this, we’d need graphics routines to allow for the same borders as we do now for fvwm/mwm.
No such external library exists (remember, this isn’t X11, so there’s no server-side to achieve this).
AFAIAC, until those libraries exist, no such fvwm-esque port can exist either.
