Dealing with rotated outputs should be much better now. As well as flipped outputs (whoever uses those), and scale factors in non-interactive screenshots that combine outputs.
Handle flipped buffer transforms
Apply transform when showing previews in screenshot/screencast dialog
Apply transform when combining screenshots of different outputs
Scale down scaled outputs when combining outputs into a single screenshot
Pass transform over pipewire, so it is handled correctly by screencast clients
