> When encoding.a triangle we perform two actions:
> 1) Make sure that the orientation of the triangle is CCW
> 2) Place the point with minimum X in the first position so we might rotate the points in the triangle.
> In this case the triangle is degenerated so when the triangle is rotated, it changes the orientation, tripping an assertion when decoding it. I think the fix for this is to change the order of the actions above.
