> This test fails for the following seed:
>  
> {{./gradlew test --tests TestXYShapeEncoding.testRandomPolygonEncoding 
> -Dtests.seed=CB4BC47404510050 -Dtests.slow=true -Dtests.badapples=true 
> -Dtests.locale=ug -Dtests.timezone=America/Matamoros -Dtests.asserts=true 
> -Dtests.file.encoding=UTF-8}}

> 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.
