PA_NO_EFFECT as incoming effect causes outgoing effect to be ignored #56

Subject of the issue

When specifying PA_NO_EFFECT as the incoming text effect for setTextEffect(), with an effect as the outgoing effect, the outgoing effect animation is ignored.

Issue description

Using the code P.setTextEffect(zone, PA_NO_EFFECT, PA_SCROLL_UP); does not scroll up text that is already being displayed.

Workaround is to specify P.setTextEffect(zone, PA_PRINT, PA_SCROLL_UP); which visually looks the same but behaves as expected with the text scrolling off the display.
