> Certain tree visits, such as the PostRestoreStateEvent delivery visit, must avoid iteration in stamping components (eg. UIData).  Before the fix for:
> TRINIDAD-2030 Honor SKIP_ITERATION FacesContext property
> This was handled in UIXComponent.visitChildren() by checking for the restore view phase.
> As of the fix for 2030, instead of checking the phase id we now check for the SKIP_ITERATION pseudo-hint.
> While this works correctly for the PostRestoreStateEvent visit, it fails in other cases.  The problem: UIXComponent.visitChildren() falls back on a "facets and children" traversal when SKIP_ITERATION is set, which means that we will visit all children (both rendered and non-rendered) even when the SKIP_UNRENDERED hint is set.
> Thus, the combination of SKIP_ITERATION and SKIP_UNRENDERED is not correctly supported with our current solution.  Since this is a valid combination of hints, we'll need an approach that correctly supports this.
