Overrides the default simplification tolerance for lines and polygons in tile pixels at and below {@code zoom}
with {@code minPixelSize}.
<p>
This replaces all previous zoom overrides that were set. To use multiple zoom-level thresholds, create a
{@link ZoomFunction} explicitly and pass it to {@link #setPixelToleranceOverrides(ZoomFunction)}
