Not sure about the percentage height code, let me know if there is a better way.

This probably introduced several bytes of padding. Is there a spare bit you can fit this into?

These "descendant has" bits are notoriously hard to keep up-to-date accurately. Is there a way to fix this without storing state like this?

Yuck.

Agreed, but sometimes it can't be avoided :) Anyway I hope I have a better solution now.

This is confusing; I feel like renderer->hasAspectRatio() could be renamed (maybe hasIntrinsicAspectRatio()).

We have other properties with the same name on both style and renderer; they generally mean the same thing, but in situations where a property does not apply to some kinds of renderers. This one is different though.

Agreed, I mixed up child.style().hasAspectRatio() and child.hasAspectRatio() quite some times in development (and vice versa). Fixed now.
