How to build a scanout backend.

Fields

fourcc: u32

The FourCC to allocate and scan out.

rotation: Rotation

The rotation the layer will be presented with, which the modifier negotiation filters against – a tiled layout a plane cannot rotate is not a candidate for a rotated layer.

vrr: VrrPolicy

Whether to ask for variable refresh.

restore: RestorePolicy

What to leave on screen at teardown.

connector_id: u32

The connector to drive; 0 for the first connected one. See ScanoutTarget::discover_connector.
