public Feature setPointLabelGridPixelSize(int maxzoom, double size) {
      return setPointLabelGridPixelSize(ZoomFunction.maxZoom(maxzoom, size));
    }
Sets the size of a grid in tile pixels that will be used to compute a "location hash" of points rendered in each
zoom-level at and below {@code maxzoom}.
<p>
This is a thin wrapper around {@link #setPointLabelGridPixelSize(ZoomFunction)}. It replaces any previous value
set for label grid size. To set multiple thresholds, use the other method directly.
