This structure contains the data for a block of graph describing a lattice,
with cylinder-shaped lrods, in an indexed form.

Used in:

PK_LATTICE_graph_data_t

This is the datatype for a graph index block of lattice data. The
graph indexed format describes each lrod via the start and end lball indices,
which are absolute to the existing lballs and the 'lball_positions' array
ordering.

Description of fields:


'n_lball_positions'     The number of lballs in the array 'lball_positions'.


'lball_positions'       The positions of the lballs of the lattice in this
                        block. There cannot be duplicates.


'lball_radii'           The radii of the lballs of the lattice in this
                        block. May be NULL if a global lball radius has been
                        specified in the options structure
                        PK_LATTICE_create_by_graph_o_t.


'lball_blend_sizes'     The sizes of the lball blends of the lattice in this
                        block. Any lballs with a blend size of zero are not
                        blended. This array may be NULL if, in the options
                        structure PK_LATTICE_create_by_graph_o_t,
                        'lball_blend_type' is PK_LBALL_blend_none_c
                        (specifying no blends) or 'lball_blend_size' is nonzero
                        (specifying a global blend size).


'n_lrod_indices'        The number of lrod indices.


'lrod_start_indices'    An array of lball indices at the start of the lrods of
                        the lattice in this block.


'lrod_end_indices'      An array of lball indices at the end of the lrods of
                        the lattice in this block.


'lrod_radii'            The radii of the lrods of the lattice in this block.
                        May be NULL if the lrod radius inheritance is not
                        PK_LROD_inherit_no_c or a global lrod radius has been
                        specified in the options structure
                        PK_LATTICE_create_by_graph_o_t.
