== [geometry] " If x and y should both be zero, the angle is s..." ==
>From Peter Hall at https://www.w3.org/Bugs/Public/show_bug.cgi?id=29786:
> https://drafts.fxtf.org/geometry-1/#dom-dommatrix-rotatefromvectorself
> 
> In the definition of rotateFromVectorSelf(x, y):
> 
> [[
>  If x and y should both be zero, the angle is specified as zero.
> ]]
> 
> This can be slightly improved to:
> 
> > If y is equal to zero and x is greater than or equal to zero, the angle is specified as zero.
> 
> The reason being that if y is zero and x is positive then there is no rotation. If x is negative then the angle is pi.
