//! Rendering a page to a raster — the one part of PDF this crate does not own.
//!
//! Reading a PDF is parsing; *drawing* one is executing its graphics, which
//! needs a rasteriser. `supported-formats.mdx` promises that a scanned PDF with
//! no extractable text returns one image per page ([#56](TECH_DEBT.md)), and
//! that promise is kept natively by PDFium, behind the default `pdf-native`
//! feature.
//!
//! On wasm32 there is no PDFium, so a text-less PDF reports that it has no
//! text. That is the only remaining behavioural difference between the SDKs for
//! PDF, and it is stated in the docs rather than papered over.
