From: Pekka Paalanen <pekka.paala...@collabora.co.uk>
The functions called here, particularly
weston_output_transform_scale_init(), rely on current mode being set.
The current mode must also be found in the mode list, though we don't
explicitly check it here.
current_mode not being set is a programmer error. It could be a backend
bug, but it could also be a libweston user bug not calling a set size
function.
