curve array enhancement

 From:  Frenchy Pilou (PILOU)
It's a vicious little problem!
All the method works fine for a circle but not for an ellipse!
Because ellipse must be divided in equal arc elliptic of the size of the triangle!
And the Array / curve (ellipse-->polyline) seems don't make that!

And if you re scale the circle to an ellipse the triangle size is modify!
