Detailed Description

Private interface shared between the thumbtable engine (thumbtable.c) and its two frontends (filemanager.c, filmstrip.c).

The engine owns the collection LUT, the thumbnail hash, populate/resize, DnD, selection and signal wiring; every place where the old code branched on dt_thumbtable_mode_t is now a call through the dt_thumbtable_layout_ops_t vtable that each frontend provides.

This header is NOT part of the public API. Only the three thumbtable translation units include it; external callers keep using dtgtk/thumbtable.h.
