Override this method to add a shader code to the beginning of each shader function (once). The shader code should be returned as a string, which can have multiple lines (the [code]"""[/code] multiline string construct can be used for convenience).
If there are multiple custom nodes of different types which use this feature the order of each insertion is undefined.
You can customize the generated code based on the shader [code]mode[/code] (see [enum Shader.Mode]) and/or [code]type[/code] (see [enum VisualShader.Type]).
