TimeShuffleFx is a special-purpose fx which is used in render-tree building

A rendering tree is a fully expanded tree that mixes implicit xsheet nesting
with
the explicit fxs dag <I> for a specific frame <\I>. Since the frame the tree
is developed from
is fixed, a sub-xsheet can be seen as a <I> frame setter <\I> fx.
