Properties of the engraver shader

The `#engraver` shader gives the effect of an engraved metal surface. You can control the size and number of etched lines by adjusting the `brightness` and `density` properties, respectively. Use these properties to work with the engraver shader:

Property | Access | Description | Default
--- | --- | --- | ---
`name` | Get and set | Name of shader | None
`brightness` | Get and set | Value controlling amount of white in shader | `0.0`
`density` | Get and set | Value controlling number of lines used to shade an area | `40.0`
`rotation` | Get and set | Angle describing 2D rotational offset for engraving lines | `0.0`
