- * @property {import("./VectorRenderType.js").default|string} [renderMode='vector'] Render mode for vector layers:
- *  * `'image'`: Vector layers are rendered as images. Great performance, but point symbols and
- *    texts are always rotated with the view and pixels are scaled during zoom animations.
- *  * `'vector'`: Vector layers are rendered as vectors. Most accurate rendering even during
