Get all quadrature points necessary to compute the interior degrees of freedom from this space, as well as the matrix that computes the degrees of freedom from the quadrature values. Degrees of freedom are interior degrees of freedom if they belong (by <A HREF="../DUALSPACE/PetscDualSpaceGetSection.html#PetscDualSpaceGetSection">PetscDualSpaceGetSection</A>()) to interior points in the reference DMPlex: complementary boundary degrees of freedom are marked as constrained in the section returned by <A HREF="../DUALSPACE/PetscDualSpaceGetSection.html#PetscDualSpaceGetSection">PetscDualSpaceGetSection</A>()).
