n_global_diffs    Number of global difference structures returned
global_diffs      Array of global difference structures
local_result      Whether the specified local comparison tests detected a
                    difference.
n_face_pairs      Number of matched face pairs found <= max_diffs
face_pairs        Array of face difference structures containing matched
                    face pairs and the differences found between them.
