It would be great. And I see no problem using an external library.

Given the size of RAW images, please try to provide load_hints (load
size, dpi, ...) and if possible try to make loader thread safe so it
will work with preload (thread that loads images). Other loaders and
not special in that, they do not provide any mutex or safeguards, but
they work as we usually don't use global data to open/decode images.
