[Openexr-devel] does half round-trip?

[Paul Miller]

I'm working on an updated Cineon I/O module, and when I use 16 bit int, 
with the Cineon log data stretched to 0-65535, I can round-trip exactly.

However, when I use half as an intermediate format with the cineon 
linearized between 0->1 (keeping super blacks and super whites), it does 
not seem to be round-tripping. It's close, and not noticable visually, 
but Shake's Common node is showing tons of "noise".

Is this expected?
