No, the wrappers have to be able to construct special-type objects on
the stack, so they cannot be abstract or marked as abstract.  This is
in contrast to vtkObject-derived types, which are always handled via
pointers.

The wrappers could be modified so that, for types such as these, the
objects are created via their copy constructor instead of via the ()
constructor.  It would require some messy parts of the wrapper code to
be re-written, though.  It isn't an easy thing to fix.
