Right.  That's a feature.

Or just don't make a copy and use the callback to free the original
data.  I think that's how it's supposed to work.

Hmm, I don't see why.  create_from_data() is a low-level interface and
doing a copy would render it useless IMHO.  If you want high level
operations then load the image from a file.  And if you can't do that
there's always the alternative of writing to the buffer returned by
get_pixels(), as Gergo suggested.
