Fixed in a slightly different way.
We still need to figure out what is the best way to handle .jp2 and .mj2.

My first feeling is that the decoder will need to support 'atom'
structure so .jp2 can be used with image2 format, maybe it does already,
I don't know.

.mj2 is ISO media with 'jp2h' atom in 'stsd', chunks of data are 'jp2c'
atoms IIRC.
