What does "based on Skia" actually mean?

Is it a fork of Skia?

Does it depend on Skia?

Did somebody look at a design diagram of Skia and redo the whole thing from scratch?

Did they read about Skia in a blogpost and get the gist of it?

In this context I would bet money that it's an implementation of the Canvas API that uses Skia underneath to do actual rasterization. It turns out (if you do a little research) that Firefox and Chrome have at various points in time used Skia as a backend for their own implementations of the Canvas API, too.

Skia is the graphics engine used by Chrome and Android to render everything: https://skia.org/

Reading the documentation, it seems to implement most (all?) of the Web Canvas API[1], and in certain areas extend the API in some exciting (well, exciting to me[2]) ways. The key point is that this can be used in the backend, far beyond the browser environment?

[2] The things that jump out to me as "exciting extensions" beyond the Api include: multiline text and text decoration (underlines!)[3]; perspective effects[4]; and Path2D boolean and filter operations[5].
