83    DMPlexInterpolatedFlag - Describes level of topological interpolatedness.
84      It is a local or collective property depending on whether it is returned by DMPlexIsInterpolated() or DMPlexIsInterpolatedCollective().
85 
86 $  DMPLEX_INTERPOLATED_INVALID - Uninitialized value (internal use only; never returned by DMPlexIsInterpolated() or DMPlexIsInterpolatedCollective())
87 $  DMPLEX_INTERPOLATED_NONE    - Mesh is not interpolated
88 $  DMPLEX_INTERPOLATED_PARTIAL - Mesh is partially interpolated. This can e.g. mean DMPlex with cells, faces and vertices but no edges represented, or a mesh with mixed cones (see DMPlexStratify() for an example)
89 $  DMPLEX_INTERPOLATED_MIXED   - Can be returned only by DMPlexIsInterpolatedCollective(), meaning that DMPlexIsInterpolated() returns different interpolatedness on different ranks
90 $  DMPLEX_INTERPOLATED_FULL    - Mesh is fully interpolated

92    Level: intermediate
