The parameters are expressions containing the following constants:
@table @option
@item E, PI, PHI
the corresponding mathematical approximated values for e
(euler number), pi (greek PI), PHI (golden ratio)
@item x, y
the computed values for @var{x} and @var{y}. They are evaluated for
each new frame.
