Description

Shadow artifacts are visible in the distance when terrain casts shadows like in the [Shadows Demo](https://sandcastle.cesium.com/?src=Shadows.html&label=All). Terrain doesn't cast shadows by default.

Research direction

Start by reproducing the artifact in the linked Shadows Demo with terrain shadow casting enabled, then investigate the terrain shadow rendering path responsible for distant shadows. Done means the distance artifacts shown in the report no longer appear while terrain continues to cast shadows.
