IDs of a set of elements which should always be rendered within this view, regardless of category and subcategory visibility. If the Viewport.isAlwaysDrawnExclusive flag is also set, only those elements in this set will be drawn.
get: Id64Set | undefined
note The Viewport.neverDrawn set takes precedence - if an element is present in both sets, it is never drawn.
