I've been working on improving the DPX/Cineon code of Blender for some
weeks now (yes, I'm a very slow coder).
With this patch, Blender is able to load every files of the
GraphicsMagick test suite (ftp://ftp.graphicsmagick.org/pub/dpx/) and
the saved DPX/Cineon now match the viewer.
I'll try to release it next week.
In the meantime, feel free to ask any questions.
