drmkit-planes

Display-plane capabilities, the layer model, and the plane allocator.

Three pieces, bottom-up:

• PlaneCapabilities and PlaneRegistry — what each plane on a device can do: which CRTCs it feeds, which formats and modifiers it scans out, whether it rotates, where its zpos may sit. Built from a device behind the device feature, or from fixtures a caller supplies, which is what lets the allocator be tested against hardware nobody has.
• Layer — one thing to put on screen, as a bag of KMS properties plus the hints that inform placement.
• Allocator — which layer goes on which plane.

Part of drmkit, a Rust port of drm-cxx. API documentation is on docs.rs.
