Yes. But then you end up with triangles in the PS file. I don't know how
big a deal that is. It must be for some, otherwise we wouldn't have done
all this :-). Some also might think that the PS-rendered strings look
better or different. But it is an easy workaround.

Yet another workaround: The trick is to get a non-null text string out to
the vector file before any other strings that could be null. One could add
a view to their viewgroup or scene so that this new view draws first (first
in container order). Put a model and single text string object containing a
space char in this view. This view and its text string will always draw
first, independent of the depth relationship of other objects and rotations,
etc.
