outlineWidth member not updating geometry

[srothst1]

This issue stems from the following community forum thread: https://community.cesium.com/t/polygon-outline-width-issue/14887

The member outlineWidth in PolygonGraphics and BoxGraphics does not change the width of the lines outlining a geometric shape if it is updated past a value of 10.

For instance, in this image outlineWidth is set to 10.

In the following image, outlineWidth is set to 100.

Clearly, there is no noticeable difference between the polygons. It is possible that this is a bug. It is also possible that this behavior is expected due to constraints unknown to me. If the latter is true, we should update the documentation.

Here are some sandcastle demos that I put together: box, polygon
