/**
 * Derives visibility state for every node in the headers tree from a ColumnVisibility port.
 *
 * For each node the following fields are updated:
 *  - `crossHiddenColumns` - visual column indices within the node's span that are currently hidden
 *  - `colspan`            - origColspan minus the number of hidden columns in the span
 *  - `isHidden`           - true when colspan drops to zero (all columns in span are hidden)
 *
 * This replaces the old hide-column / show-column node modifiers, which could not handle
 * external hides inside collapsible groups (DEV-294).
