 * Given a list of compatible Mesh {@link Primitive Primitives}, returns new Primitive

 * same {@link Material Materials}, draw mode, and vertex attribute types. Primitives
 * using morph targets cannot currently be joined.
 *
 * Example:
 *
 * ```javascript
 * import { joinPrimitives } from '@gltf-transform/functions';
 *
 * // Succeeds if Primitives are compatible, or throws an error.
 * const result = joinPrimitives(mesh.listPrimitives());
 *
 * for (const prim of mesh.listPrimitives()) {
 * 	prim.dispose();
 * }
 *
 * mesh.addPrimitive(result);
 * ```
