A simple example that shows how to use *resvg* from GTK+ through C-API.

I'm not good with C and GTK+ so any suggestions are welcome.

## Run

```bash
# build C-API with a cairo backend first
cargo build --release --features "cairo-backend" --manifest-path ../../capi/Cargo.toml
make
LD_LIBRARY_PATH=../../target/debug ./example image.svg
```

See [BUILD.adoc](../../BUILD.adoc) for details.
