Test suite breaking with new `svglite` release

[grantmcdermott]

I'm not sure exactly what's happening, but I can reproduce the latest CI failure on my local machine after updating svglite to the latest 2.2.0 release.

I might just try to re-render all test snapshots with the new engine / version and hope that this solves everything.

(As an aside: the svglite release is also breaking tests in some of my other CRAN packages, so that's how I knew to look there...)

FYI: {vdiffr} embeds an older and less frequently updated version of svglite::svglite() precisely so snapshot tests need to be updated less frequently.

vdiffr works with testthat, but tinyplot uses tinytest.

Theoretically I think you could still use vdiffr:::svglite() or vdiffr::write_svg() instead of using svglite::svglite() with tinytest. But maybe the benefit of less frequent snapshot updates outways the cost especially if you want to test the new graphics features like gradients, patterns, compositing operators, etc that {vdiffr} doesn't support yet.
