[Bf-committers] Color space and alpha issues

I thought I'd add the "infamous" thread over at Adobe here regarding
associated versus unassociated alpha in the context of a system that
needs to support various formats.

In this case, for those unfamiliar, this was the thread in which Adobe
responded to their (mis) handling of the EXR format.

The players here are:

Zap Andersson - seasoned image professional now with Autodesk.
Florian Kainz - architect of the EXR specification.
Chris Cox - veteran architect at Adobe.


TL;DR version:

Unassociated alpha systems cannot adequately deal with the inherent
specifics of associated alpha systems.

I've also added a "Further Reading" section to Brecht's page.

Hope someone finds it insightful,
