Description
First, rawspeed looks like a great library, thanks to all who worked hard on it. I've been reading through the source and I think I know the answer, but is it possible to access raw image data without full loading the resulting cfa channels into memory? (for example to load the image in tiles or by scanline or something). I'm combining multiple raw files at a time and need to only load part of them in ram at once. Any help would be appreciated. If its not possible, how difficult would it be to modify rawspeed (I could probably fund some development if its something thats not a huge change) Thanks!

Research direction
The issue does not name a file, test, or entry point. Start by tracing how rawspeed loads decoded CFA channels into memory, then determine the scope of tile or scanline access and define completion around reading only requested portions without full in-memory loading.
