4.2.11 GROUP Files

This format is obsolete, but is still accepted. It combined the functions of INST and TLIST, taking a series of transformations and a single Geom (unit) object, and replicating the object under each transformation.

GROUP ... < matrices > ... unit { oogl-object }

is still accepted and effectively translated into

INST transforms { TLIST ... <matrices> ... } unit { oogl-object }
