Compile error for custom member function `sample_ray_differential` in `emitter.h`

Hi @realWDC ,

Could you try to do the following in ray.h:

ENOKI_DERIVED_STRUCT(RayDifferential, Base,
    ENOKI_BASE_FIELDS(o, d, d_rcp, mint, maxt, time, wavelengths),
    ENOKI_DERIVED_FIELDS(o_x, o_y, d_x, d_y, has_differentials) // <-- REMOVE has_differentials
)

[realWDC]

In ray.h after removing has_differentials, thank you @Speierers now it works:

ENOKI_DERIVED_STRUCT(RayDifferential, Base,
    ENOKI_BASE_FIELDS(o, d, d_rcp, mint, maxt, time, wavelengths),
    ENOKI_DERIVED_FIELDS(o_x, o_y, d_x, d_y) // `has_differentials` removed
)

// ...

ENOKI_STRUCT_SUPPORT(mitsuba::RayDifferential, o, d, d_rcp, mint, maxt,
                     time, wavelengths, o_x, o_y, d_x, d_y) // // `has_differentials` removed
