MaterialListSource

What a MaterialListModel lists: the ids, and for each the facts it sorts by, without a record (rendering-revamp §RVM-9, scale).

In the namespace construct::model. Declared in src/libs/libconstruct/construct/model/MaterialListModel.hpp.

Detailed description

The library's records and a document's scene records are one source, the model's own. A test lists a million generated records through a source of its own, which makes a record only for a row that is shown.
