* Fix: Disabled radius tapering on 2d curves with filled front or back. It would be
really cool to get this working solidly, but there are many potential problems with the
triangle face creation across the flat surfaces, especially when there are holes inside
the curves. Maybe this could be a fun project for someone better at this than I? :)
Taper object curves still cause similar problems...

* Made the curve radius affect the 'Nsize' curve normal drawing too, so you don't need a
bevel to see the value.
