lyon VS rustybuzz

Where is the changelog? https://github.com/nical/lyon/blob/master/CHANGELOG.md is not up to date.

In fact, if using a modern graphics pipeline with shaders, you will actually have to learn how to draw a single rectangle to your screen, and then use that knowledge to draw (anti-aliased) lines, rectangles, arcs, circles, ellipses, etc. too. For instance, have a look at https://www.cairographics.org/ https://github.com/vurtun/nuklear https://github.com/memononen/nanovg and https://github.com/nical/lyon. There are probably also tutorials on how to draw vectorized graphics using OpenGL, Vulkan, etc.

Use Lyno or pathfinder to render font or svg

Bit of a side note, but COSMIC depends on the rustybuzz text shaper which is deprecated: https://github.com/RazrFalcon/rustybuzz/issues/74. There was some work underway to bring it up to sync with the latest harfbuzz and then handing over ownership to the harfbuzz team, but this seems to have fizzled out.

I understand that this may sound harsh, but I also ported two (far bigger) codebases from C++ to Rust: rustybuzz and tiny-skia. Both of which are production -ready and not just prototypes. And mine not only do not use pointers, but also barely use unsafe in general.

harfbuzz is a popular library for text rendering. You may also want to check out rustybuzz, a small subset of harfbuzz ported to Rust with pretty great documentation.

Use allsorts or rustbuzz for text shaping

Yeah Allsorts looks interesting, and rustybuzz is another option. I haven’t tried either yet, though.
