The size of the node in the visual shader graph.
Construct a new instance of VisualShaderNodeGroupBase. Note: use memnew!VisualShaderNodeGroupBase instead.
Base class for a family of nodes with variable amount of input and output ports within the visual shader graph.
Currently, has no direct usage, use the derived classes instead.
