Description
Please click on each of the following three screenshots to see that compared to Chrome and Femtovg, the Vello rendering results have obvious small jagged edges on the beard.
PS: Femtovg rendering results also had small jagged, similar to Vello, but after changing the `dpi_factor` to 1.0, it seems to be not inferior to Chrome.

Research direction
Start by reproducing the three screenshot comparisons and checking the linked Femtovg example at examples/svg.rs around line 145, including its dpi_factor setting. Compare Vello's beard edges with Chrome and Femtovg; done means identifying a concrete anti-aliasing improvement and showing visibly smoother results, ideally with a repeatable test or comparison.
