A utility node which allows the positioning of other nodes on a coloured backdrop with optional text. Selecting a backdrop in the ui selects all the nodes positioned on it, and moving it moves them with it.
Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.
The title for the backdrop - this will be displayed at the top of the backdrop.
Controls the size of the backdrop text.
Text describing the contents of the backdrop - this will be displayed below the title.
