`fframes_kit::paths` has Remotion's `@remotion/paths` in snake_case over `kurbo::BezPath`:
`get_length`, `get_point_at_length`, `get_tangent_at_length`, `evolve_path`,
`interpolate_path`, `translate_path`, `scale_path`, `reverse_path`, `cut_path`, `warp_path`,
`normalize_path`, `get_bounding_box`, `get_subpaths`, `extend_view_box`, `center_path`,
`parse_path`, `serialize`, `reset_path`, `reduce_instructions`, and `align_points(a, b, n)`
(the same number of subpaths and cubic segments in both, turned to start at the nearest
points), which `Morph` runs on.

```rust
use fframes_kit::prelude::*;

let square = paths::parse_path("M0 0 L10 0 L10 10 L0 10 Z").unwrap();
assert_eq!(paths::get_length(&square), 40.0);
assert_eq!(paths::get_length(&paths::cut_path(&square, 20.0)), 20.0);
let half = paths::interpolate_path(0.5, &square, &paths::scale_path(&square, 2.0, 2.0));
assert!((paths::get_bounding_box(&half).width() - 15.0).abs() < 1e-9);
