[Tig] GraphicsMagick and Kodak Cineon format

[Bob Friesenhahn]

As some of you are aware, GraphicsMagick's Kodak Cineon (.cin) writer 
has been broken for a long time.  I spent a day this past weekend to 
find out why and to fix the writer.  It turns out that the reason for 
brokenness was simple, but the complete writer was junk so I rewrote 
it from scratch so it preserves metadata and provides maximum 
interoperability with SMPTE DPX.  This way as much header information 
as possible is passed when translating back and forth between .dpx and 
.cin formats.

As soon as the Cineon support passes all of its tests, then I will 
create a new snapshot.  In the mean time the latest source code is in 
GraphicsMagick CVS.  There seems to be some incremental data loss when 
GraphicsMagick is built to support 8-bit samples, but (apparently) not 
when it is built to support 16-bit samples.  Data loss is not 
acceptable for any source snapshot.

I am looking for a few brave volunteers capable of compiling 
GraphicsMagick from source code to help me test and prove the Cineon 
support in GraphicsMagick so that it is something which can be 
completely relied upon.

Thanks,

Bob
