[fluxus] procedural modelling

[Dave Griffiths]

Hi all,

I originally wrote the turtle as an experiment for procedural modelling
that I never got that far with - I've done quite a lot with it for 2D
shapes but only just got round to doing more complex things:

The latest release has this as an example - I also fixed recalc-normals
for triangle strip polygon primitives.

cheers,
