	<description>
		Custom Godot Shading Language expression, with a custom amount of input and output ports.
		The provided code is directly injected into the graph's matching shader function ([code]vertex[/code], [code]fragment[/code], or [code]light[/code]), so it cannot be used to declare functions, varyings, uniforms, or global constants. See [VisualShaderNodeGlobalExpression] for such global definitions.
