// Catalog of every pixel format the C++ side handles. The X-macro is a
// flat list of names:
//
//   X(name)
//
// `name` is the canonical format identifier — both an internal FormatId
// enum entry and the public string accepted by pixpat_buffer::format.
// Each name resolves to a struct in `pixpat::formats::` (defined under
// pixpat-native/src/formats/) that carries:
//
//   - the layout (subsampling, planes, components)
//   - nested `Source` / `Sink` aliases for the matching I/O templates
//
// Adding a format = a row here AND a struct in the right
// pixpat-native/src/formats/*.h. The codegen
// (pixpat-native/codegen/gen_pixpat.py) parses this X-macro to learn
// the format set; pixpat.cpp re-expands it to build s_format_info via
// `formats::name::Source` / `formats::name::Sink`.
//
// FormatId is internal — the public C ABI deals in format names only.
