This function sets edges to have a constant 'radius' blend.

This function offers partial support for facet geometry [PF]


Specific Errors:
    PK_ERROR_bad_blend_param     illegal combination of blend properties
                                 (MILD)

    PK_ERROR_general_body        edges are from a general body
                                 (MILD)

    PK_ERROR_tolerance_too_loose The supplied or edge tolerance is too large
                                 compared to the blend radius
                                 (MILD)

    PK_ERROR_bad_tolerance       specified tolerance is too tight
                                 (MILD)



Attaches unfixed constant radius blends to a given array of edges.

The argument 'radius' is the radius of the rolling ball and must be greater
than twice the maximum tolerance of all edges in 'edges' and their associated
vertices. If the supplied tolerance is applicable, the radius of the rolling
ball must also be greater than twice the supplied tolerance.

A successful result will produce a new blend attribute. It will return
the edge(s) to which the blend attribute is attached in the array
'blend_edges'.

See PK_BODY_fix_blends for making the blends a part of the topology.

Blends can be created on general bodies, so long as the portion of the body in
the neighbourhood of the blend is locally manifold.
