Render a geometric entity throgh GO as a view independant wire frame drawing


Specific Errors:
    PK_ERROR_duplicate_array_item   geom has duplicates but no transf array
    PK_ERROR_bad_component          geom transf is inappropriate


This function produces a 3D line drawing of geometric entities in the world
coordinate system via GO. The geometric entities supported are B-curves and
B-surfaces, foreign geometry curves and surfaces and offsets of B-surfaces
and foreign geometry surfaces. Other geometric types are simply ignored.

If geom_transfs is set to NULL, entities in geoms are not transformed.
The geoms array may not contain duplicates in this case.

If geom_transfs is not set to NULL, it refers to an array of TRANSFs of
length n_geoms. The geoms array may contain duplicates in this case.
Each entity in geoms is transformed by the corresponding entry in
geom_transfs. The 'geom_transfs' matrices may not contain perspective terms.
They may only contain translation and rotation components. Reflections, scales
and shears are not allowed.

If a geom_transfs entry is set to PK_ENTITY_null, it implies that the
corresponding entity in geoms is not to be transformed.
