Would it be possible to use rayon to add parallel iterators over the image pixels or add multithreading from scratch?

Would adding multi-threading or parallel iterators to access pixels be feasible? Is it potentially planned for the future?

I wondered about this too. AFAIK, iterating over pixels in parallel currently requires ugly code (uglier than a Rayon iterator, at least).

Is it necessary to add multi-threading? I was thinking about how it would benefit the imageproc crate, at least on large images, but maybe it would be better handled by the GPU.
