// FIXME: this queries layer compositing state - which is not
// supported during layout. Hence, the result may not include all CSS
// transforms.

// We can stop at compositing layers, to match the backing resolution.
// FIXME: should we be computing the transform to the nearest composited
// layer, or the nearest composited layer that does not paint into its
// ancestor? I think this is the nearest composited ancestor since we will
// inherit its transforms in the composited layer tree.
