A Decade of Slug

Vello is intended more for general vector graphics and would probably perform better with pictures containing lots of large paths. Slug is designed specifically for rendering glyph-like objects and would perform better with lots of text and icons.

I was going to ask if Slug can be used as a general vector renderer. Or does it assume limits on e.g. number of curves/paths per area that are typical of fonts?

Eric answered a similar question on the Discord channel saying Slug is suitable for generic vector graphics. He recommends checking out the demo at https://sluglibrary.com/ (you can cycle through the examples with the space bar).

I think it is limited to integral quadratic bezier curves, which is sufficient for text rendering. But general purpose vector graphics almost certainly want rational cubic bezier curves too.

The Slug Library can convert each cubic curve into a small set of quadratic curves that approximate extremely well.
