Dumping unmodified raw image data from raw files?

Basically for these files, the difficulty arises because there is currently no meaningful data_offset and data_size because libraw loads and processes the files on the fly, and not into memory.

Give me a make/model of camera that libraw handles that way, and I’ll get a DPReview raw file from that camera and poke around the file structure. For NEFs, I can divine the offset and size from the metadata, without need for libraw.
