Sigh. CurvierCurves-wiz.7.cs is back in Alpha status. 

I found a bug when curvier smoothing is used w/
polygons with large number of vertices. ( large is
~30. If the vertices are rounded to integers the
problem holds off till ~50. So its clearly an
accumulation of errors type bug.  Unfortunately
polygons can get VERY large due to this instabiltity
and the result is a sad show stopper. Back to the
drawing board.)

With the curvier preference turned off everything
seems safe. And I expect putting the more mundane
method of calculating closed curve slopes back in will
make things more robust. So this is a temporary
setback. But I entent to take some time to do some
mourning and to do a proper post mortem. 

"In theory, theory and practice are the same. In
practice the're not."

Yours in Service, --Jerome Peace
