Subject: [PATCH] Remove unused properties from the `Shadings`-implementations
 in `src/core/pattern.js`

Neither the `type` or the `cs` properties are used outside of the "constructors", and we can thus remove them.[1]
Note that a lot of this code is very old, and that it actually predates the main/worker-thread split before which the *same* file was used on both the main- *and* worker-threads.

---
[1] On the main-thread, a similar `type` property was removed in PR 12591.
