I don't understand the first point, could you clarify? Do you mean you wish to define your own CSS properties? You may find it exciting to learn that there's ongoing work to enable this functionality and more through Houdini [0]. You can check out a few examples at this houdini-samples [1] repo. I'm unclear on what you mean by wrapping limits and non-linear image scaling. Could you provide an example of what you'd like to achieve? As for having to optimize for width or height. Have you looked into display: grid? I believe it may help enable the kind of layout you're interesting in achieving.
