PDF page rasterizer in pure Rust — vello-backed rendering, no PDFium, WASM-compatible.

It is used by the [PDFluent](https://pdfluent.com) Rust PDF SDK, on the
upstream terms: **Apache-2.0 OR MIT**, for the whole crate, PDFluent's
extensions included.

## What it does

Rasterizes PDF pages to raster images (PNG, JPEG, raw pixel buffers). Uses `vello_cpu` for content-stream rendering — no C++ dependency, compiles to WebAssembly, and is compared against a reference renderer by SSIM in the release gate.

## Status

Rendering fidelity is measured by SSIM against a reference renderer on a fixed corpus. The figures are published with a claim ID at <https://pdfluent.com/benchmarks/how-we-measure>; none are repeated here. Improvement work continues on near-miss cases.

## Usage

Most users do not depend on this crate directly. Use the [`pdfluent`](https://crates.io/crates/pdfluent) facade or [`pdf-engine`](https://crates.io/crates/pdf-engine):

```rust
use pdfluent::prelude::*;
```

For low-level access, see <https://pdfluent.com/docs>.

## License

**Apache-2.0 OR MIT** — preserved from upstream `hayro`. Relicensing is
prohibited, so how far this fork is extended does not move it: the extensions
are licensed on the same terms as the code they were built on. The upstream
attributions are in `THIRD_PARTY_LICENSES.txt` in the repository root.
