Description
Hey @RazrFalcon, I hope you're doing OK.
There is a weird issue with text resolving that was caught for one particular font and a combination of letters. Not sure exactly on which level that happens - either `usvg-text-layout` or `rustybuzz`. Maybe you have an idea?
SVG:
```
```
Font Fjalla One (https://fonts.google.com/specimen/Fjalla+One?noto.query=Roboto&preview.text=fit&preview.text_type=custom&query=fjalla)
Result of running `minimal.rs` example with added `fontdb.load_font_file("./examples/Fjalla One-regular.ttf").unwrap();`
Expected (rsvg-convert):
Actual (ReSVG):

Research direction
Start with the minimal.rs example and the provided Fjalla One-regular.ttf font, reproducing the `fit` rendering from the issue. Trace text shaping through `usvg-text-layout` and `rustybuzz` to identify where the letter overlap is introduced. Done means the rendered SVG matches the expected reference for this font and letter combination.
