The intention is to base all formats except textDevice and browser on
UTDML. This is because in the case of volumes, for example, utd provides
a first pass over the material, which is then intended to be used in
determining volume size, etc. In all formats except textDevice and
browser utd provides the basis for including images and different cell
sizes.
Do not change this code. It would result in a major rewrite. If utd is
working for a given document the problem is in the conversion modules,
such as utd2volumes or utd2brf .
