Determines whether the effect should hide the focus ring
when starting the effect.
The effect target is responsible for the hiding the focus ring.
Subclasses of the UIComponent class hide the focus ring automatically.
If the effect target is not a subclass of the UIComponent class,
add functionality to it to hide the focus ring.
<p>Set this property to <code>true</code>

method when the effect is part of a transition.
<p>Use this function when you want the effect to figure out the start
and end values of the effect.
The proper usage of this function is to use it
in the following steps:</p>
<ol>
<li>Call the <code>captureStartValues()</code> method.
The effect captures the starting effect values.</li>
<li>Make changes to your effect targets, such as
adding/removing children, altering properties,
changing location, or changing dimensions.</li>
<li>Call the <code>play()</code> method.
The effect captures the end values.
This function populates the
<code>EffectInstance.propertyChanges</code> property
for each effect instance created by this effect.
Effect developers can use the <code>propertyChanges</code> property
to retrieve the start and end values for their effect.</li>

Creates a single effect instance and initializes it.
Use this method instead of the <code>play()</code> method

<p>The effect instance is created with the type
specified in the <code>instanceClass</code> property.
It is then initialized using the <code>initInstance()</code> method.
If the instance was created by the EffectManager
(when the effect is triggered by an effect trigger),
the effect is further initialized by a call to the
<code>EffectInstance.initEffect()</code> method.</p>
<p>Calling the <code>createInstance()</code> method

Stops the effect, leaving the effect targets in their current state.
Unlike a call to the <code>pause()</code> method,
you cannot call the <code>resume()</code> method after calling
the <code>stop()</code> method.
However, you can call the <code>play()</code> method to restart the effect.
<p>The effect instance dispatches an <code>effectEnd</code> event
when you call this method as part of ending the effect.</p>
<p>For mask effects, the mask is not removed automatically
when the effect is stopped.
Running further mask effects on the same target(s)
without first removing the mask can produce unexpected results.</p>
