Jono, see this: https://github.com/OpenImageIO/oiio/pull/1167
This adds a set_pixels (and in the Python binding, it takes either a tuple or a
Python array). It's probably not super efficient (ick, there's an intermediate
copy to a std::vector involved), but it's a start.
I'm not experienced enough with numpy to know; how would you want the Python
API to look to be most efficient for your purposes?
