/* FIXME: Temporary workaround for a bug in the oneAPI + Embree backend that sometimes sets
* the SR_BSDF_HAS_DISPERSION flag when calling `surface_shader_eval` inside the MNEE code
* path. This happens even in scenes where no material uses dispersion. This workaround
* disables dispersion support + MNEE for all oneAPI backends. Proper fix should be on the
* oneAPI side. */
