The ability to add entities and fields to a paint tableau in a way that makes them PAINTED (i.e. $entinfo or $fieldinfo will report them as being physically there), but does not take up any physical space on the form.
\"To ensure that \"\"hidden\"\" fields are truly hidden, so that they take up none of the valuable real estate available on a form. Also to ensure that entities that are referenced in the logic but are not intended to show any visible fields do not take up any space on the form.\"
