I'm not sure yet :) I just would like to make also normal vobs dice and
then test if distorted coordinate systems could be somehow used in
"general" views (at least in my BubbleView).

I wonder, how text renderables could be made dice?

And does this make rendering too s l o w ?-)

It would abstract things like VanishingClient, but not totally hiding the
coordinate systems. I'll put these soon (tomorrow) into the generalizing
vanishing view peg. E.g.:

  Vanishing client has:
   void place(Cell c, java.lang.Object o, float fract, int x0, int y0, int
            x1, int y1, int depth, float rot)

  ViewTool would have something like (probably some of the parameters are
  irrelevant):
   int place(cs into, Cell c, java.lang.Object o, float fract, int x0,
             int y0, int x1, int y1, int depth, float rot)

So, ViewTool won't do the vs.put(), but returns a new coordsys for
correct placing. I don't know yet how ViewTool's connect should work,
though, connection needs two coordinate systems.

Currently connections are created in View like: new SimpleConnection(1,
0.5f, 0, 0.5f); Those parameters are depending the direction of the
connections. As connection is drawn by put(conn, cs1, cs2), this
one goes from the right side of first coordsys's box to the left side of
the second coordsys's box.

The first proposed solution was to only ask those connection
mount parameters from the CellView (BoxCellView wants the connection to be
mounted in the middle of its side, LollipopCellView wants the connection
to be mounted on its circle's edge). Benja thought that this won't
work with fillets because fillets should be also drawn differently with
different CVs (again, the LollipopCellView is an exception, where only its
circle should fillet).

So, now its proposed that CellView creates connection vob for wanted
direction from the given cell and returns it to View.
