/**
FIXED-POSITION FRAMES AND Z-ORDERING
Fixed-position frames are special. They have TWO views. There is the "real" view, which is
a child of the root view for the viewport (which is the root view of the view manager).
There is also a "placeholder" view (of class nsZPlaceholderView) which never really
participates in any view operations. It is a child of the view that would have contained
the fixed-position element if it had not been fixed-position. The real view keeps track
of the placeholder view and returns the placeholder view when you call GetZParent on the
real view.
(Although currently all views which have a placeholder view are themselves children of the
root view, we don't want to depend on this. Later we might want to support views that
are fixed relative to some container other than the viewport.)
As we build the display list in CreateDisplayList, once we've processed the parent of
real views (i.e., the root), we move those real views from their current position in the
display list over to where their placeholder views are in the display list. This ensures that
views get repainted in the order they would have been repainted in the absence of
fixed-position frames.
