display band (display area vs real visible area)

[Michael Nazzareno Trimarchi]

Hi all

I would like to know the best approach in the graphics subsystem how
deal with panels where the display area is different from the visible
area because the display has a band left and right. I have already
done the drm driver for the panel but from userspace point of view
it's a pain to deal in wayland for input device and output device. Do
you have any suggestions?

Regards
Michael
