* @defgroup PartInfo Part related definitions.
*
* A part is a separate entity in the OpenEXR file. This was
* formalized in the OpenEXR 2.0 timeframe to allow there to be a
* clear set of eyes for stereo, or just a simple list of AOVs within
* a single OpenEXR file. Prior, it was managed by name convention,
* but with a multi-part file, they are clearly separate types, and
* can have separate behavior.
*
* This is a set of functions to query, or set up when writing, that
* set of parts within a file. This remains backward compatible to
* OpenEXR files from before this change, in that a file with a single
* part is a subset of a multi-part file. As a special case, creating
* a file with a single part will write out as if it is a file which
* is not multi-part aware, so as to be compatible with those old
* libraries.
