fn to_animated_zero(&self) -> Result<Self, ()>

Returns a value that, when added with an underlying value, will produce the underlying value. This is used for SMIL animation’s “by-animation” where SMIL first interpolates from the zero value to the ‘by’ value, and then adds the result to the underlying value.

fn to_3d_matrix( &self, reference_box: Option<&Rect<ComputedLength>> ) -> Result<Transform3D<f64>, ()>

If |reference_box| is None, we will drop the percent part from translate because we cannot resolve it without the layout info, for computed TransformOperation. However, for specified TransformOperation, we will return Err(()) if there is any relative lengths because the only caller, DOMMatrix, doesn’t accept relative lengths.
