+ 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.
