`xr`

  Type: `double*`

  The X-coordinate of the red primary.

  The argument will be set by the function.
  The argument can be `NULL`.

`yr`

  Type: `double*`

  The Y-coordinate of the red primary.

  The argument will be set by the function.
  The argument can be `NULL`.

`xg`

  Type: `double*`

  The X-coordinate of the blue primary.

  The argument will be set by the function.
  The argument can be `NULL`.

`yg`

  Type: `double*`

  The argument can be `NULL`.
  The caller of the function takes ownership of the returned data, and is responsible for freeing it.

`blue_trc`

  Type: `Babl`

  The blue component of the TRC (can be `NULL` if it’s the same as `red_trc`).
