Detailed Description

One registered atlas image (private to the binder; treat as opaque).

Book-backed sources (book != NULL) read tiles off a stored archive entry at path; external sources read through their own pread seam (pread/pread_ctx).

Invariant: Exactly one of book or pread is non-NULL while registered.

Since: 0.1.0
