Depending on the shader type, you can override different processor functions.
For ``spatial`` and ``canvas_item``, you have access to ``vertex()``,
``fragment()``, and ``light()``. For ``particles``, you only have access to

The ``fragment()`` processing function is used to set up the Godot material

The standard use of the fragment function is to set up material properties used
to calculate lighting. For example, you would set values for ``ROUGHNESS``,
