default T setAttrWithMinzoom(String key, Object value, int minzoom) {
      return setAttr(key, ZoomFunction.minZoom(minzoom, value));
    }
Sets the value for {@code key} attribute at or above {@code minzoom}. Below {@code minzoom} it will be ignored.
<p>
Replaces all previous value that has been for {@code key} at any zoom level. To have a value that changes at
multiple zoom level thresholds, call {@link #setAttr(String, Object)} with a manually-constructed
{@link ZoomFunction} value.
