The edge tessellation factors, with each index value providing the tessellation factor for a particular edge.

```
var edgeTessellationFactor: (UInt16, UInt16, UInt16, UInt16)
```

## Discussion

- The value in index 0 provides the tessellation factor for the left edge of the patch.
- The value in index 1 provides the tessellation factor for the top edge of the patch.
- The value in index 2 provides the tessellation factor for the right edge of the patch.
- The value in index 3 provides the tessellation factor for the bottom edge of the patch.
