Returns the shader's code as the user has written it, not the full generated code used internally.

Returns the shader's custom defines. Custom defines can be used in Godot to add GLSL preprocessor directives (e.g: extensions) required for the shader logic.
[b]Note:[/b] Custom defines are not validated by the Godot shader parser, so care should be taken when using them.
