Description
To ensure that our pipeline is reaching results as expected, it would be good to compare our snapshot tests against existing rendering systems. These could include:
- skia
- tiny-skia
- webrender
- cocoa
- Browser rendering of SVGs
Some of this could be tested by using [Piet](https://github.com/linebender/piet). The existing tests for Piet can be found in https://github.com/linebender/piet-snapshots, which we could bring up as Vello tests.
This should all happen in CI, as these tests are not useful if they can only be run locally.

Research direction
Start by reviewing Vello's existing snapshot tests and the Piet tests in the linked piet-snapshots repository. Determine how comparisons with Skia, tiny-skia, WebRender, Cocoa, and browser SVG rendering can run in CI. Done means the selected renderer comparisons execute reliably as CI tests.
