/*!
`tiny-skia` is a tiny [Skia](https://skia.org/) subset ported to Rust.

`tiny-skia` API is a bit unconventional.
It doesn't look like cairo, QPainter (Qt), HTML Canvas or even Skia itself.
Instead, `tiny-skia` provides a set of low-level drawing APIs
and a user should manage the world transform, clipping mask and style manually.

See the `examples/` directory for usage examples.
