is_consistent()

Check that every field is densely populated over the lattice.

Verifies a nonzero lattice, at least one field, no empty or duplicated names, and that each field holds exactly cell_count() elements.

Producers should invoke this before handing the data to a writer. Writers should invoke it before trusting any pointer they take from it, as EXRWriter does with ImageData.
