Description

A few utilities and class instances for `Active` (from the `active` package). In particular, this module defines

- An instance of `V` for `Active`: ``V` (`Active` a) = `V` a`
- `HasOrigin`, `Transformable`, and `HasStyle` instances for `Active` which all work pointwise.
- A `TrailLike` instance for ``Active` p` where `p` is also `TrailLike`, which simply lifts a pathlike thing to a constant active value.
- A `Juxtaposable` instance for ``Active` a` where `a` is also `Juxtaposable`. An active value can be juxtaposed against another by doing the juxtaposition pointwise over time. The era of `juxtapose v a1 a2` will be the same as the era of `a2`, unless `a2` is constant, in which case it will be the era of `a1`. (Note that `juxtapose v a1 a2` and `liftA2 (juxtapose v) a1 a2` therefore have different semantics: the second is an active value whose era is the combination of the eras of `a1` and `a2`).
- An `Alignable` instance for ``Active` a` where `a` is also `Alignable`; the active value is aligned pointwise over time.
