Detailed Description

The IFF clip chunk of a native animation resource.

Clip chunks are optional within a file. If no clip chunk is present, the individual keys are stored at the root level of the chunk hierarchy, and the animation only consists of a single clip with start/end time taken from the header chunk. If there is at least one clip chunk present, there must not be any key chunks at the root level; instead, all key chunks belonging to a single clip can be found as sub-chunks in the data block pointed to by the clip chunk's mDataOffset member.
