The object I need to pass around is the 3D model equivalent of the
FP_LIB_TABLE object
so I thought Prj() would be the most convenient place to put it.
Alternatively I can make it a
single global but it must be notified when the project working directory
changes.

The specific problem I have at the moment has to do with
3d-viewer/3d_class.cpp;
in S3D_MASTER::SetShape3DName the m_Shape3DFullFilename is determined,
so I need access to the 3D Model Manager which I put into Prj(). This is
something of
a stop-gap measure since Mario is working on replacing the rendering system
and we
plan to make the large and complex S3D_MASTER object disappear so that
MODULE
will only hold pointers to an extremely simple structure which only
contains a filename,
offset, rotation, and scale. That would essentially remove all information
which MODULE
really isn't responsible for and the 3d cache will take responsibility for
holding and
managing the 3D data.

Is there any current method for a class like S3D_MASTER to obtain a
pointer/reference
to a KIWAY or Prj()?
