PETSc version 3.15.4
sets of IS's that define a coloring of the underlying indices
typedef struct _n_ISColoring* ISColoring;
One should not access the *is records below directly because they may not yet
have been created. One should use ISColoringGetIS() to make sure they are
created when needed.
When the coloring type is IS_COLORING_LOCAL the coloring is in the local ordering of the unknowns.
That is the matching the local (ghosted) vector; a local to global mapping must be applied to map
them to the global ordering.
Developer Note: this is not a PetscObject
