typedef int PK_blend_identify_t;
Terminology:
A "branch face" is any blend face that splits a chain of blends into two or
more branches.
A "minimal chain" of blends is terminated by any branch face that is not in
the given faces
A "maximal chain" of blends includes any branch faces and the chains emanating
from those branch faces.
This datatype allows the user to specify how blend faces are identified from
a given set of faces. It has the following values:
PK_blend_identify_within_c only blend faces within the given face set are
identified
PK_blend_identify_exc_chain_c minimal chains of blends starting within the
given face set and excluding final branch faces.
PK_blend_identify_inc_chain_c minimal chains of blends starting within the
given face set and including final branch faces.
PK_blend_identify_max_chain_c maximal chains of blends starting within the
given face set.
PK_blend_identify_dependent_c blends not in the face set but dependent on
faces within the given face set are identified.
