Variablebackground (GUI item property)
This may be needed when the background property uses a variable instead of a constant value, but it does not appear to be a real property. Variable-based background properties do function without this property, but the texture referred to draws absolutely-last, even drawing on top of the GUI cursor. This property would appear to be a workaround, but it does not appear to function, and is not referenced on iddevnet.
