Backdrop
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.
user
Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.
title
The title for the backdrop - this will be displayed at the top of the backdrop.
scale
Controls the size of the backdrop text.
description
Text describing the contents of the backdrop - this will be displayed below the title.
depth
Determines the drawing order of overlapping backdrops.
Note
Larger backdrops are automatically drawn behind smaller ones, so it is only necessary to manually assign a depth in rare cases where this is not desirable.
