Label outline aliasing

[dslming]

Label outline aliasing when font size is big.

const viewer = new Cesium.Viewer("cesiumContainer");
viewer.scene.globe.show = false;

viewer.entities.add({
      position: new Cesium.Cartesian3(0, 0, 0),
      label: {
        text: "Cesium",
        font: "128px 微软雅黑",
        scale: 2,
        fillColor: new Cesium.Color(255 / 255, 255 / 255, 255 / 255),
        showBackground: false,
        outlineColor: Cesium.Color.RED,
        outlineWidth: 2,
        style: Cesium.LabelStyle.FILL_AND_OUTLINE,
      },
    });
