There are implementation implications. Currently, implementations can internally reduce any calc to an array of coefficients. (Element dimensions, font size, device orientation might change during an animation, so a calc can't simply be represented as a number of pixels.)

This proposal requires a slow path of general expression evaluation during each frame's style calculation. 

Suppose we have animation between `min(10%, 20vw)` and `max(30em, 40vh)`.

At 75% progress, the result is
`calc(0.75 * min(10%, 20vw) + 0.25 * max(30em, 40vh))`
