Reset effect when user changes effect parameters

Fix resets the (corona) effect accumulation that would eventually paint
the entire screen for Fade parameter 1.0. Now changing any parameters for
the effect resets the effect and allows the user to see the actual impact
of current parameters without carryover from previously rendered frames,
for shader effects that accumulate.
