The Fade effect animates the
alpha property of a component,
either from transparent to opaque, or from opaque to transparent.
If you specify the Fade effect for the showEffect
or hideEffect trigger, and if you omit values for the
alphaFrom and alphaTo properties,
the effect automatically transitions alpha from 0
to the target's current alpha value on a
showEffect trigger, and from the target's current
alpha value to 0 on a hideEffect trigger.
Note: To use the Fade effect with text, you must use an embedded font, not a device font.
