Description

Steps to reproduce:
1. Create an s:Application
2. Set its backgroundAlpha value to 0 to make it transparent

Actual Results:
When the app is loaded inside another application the background is not transparent. The default ApplicationSkin doesn't take this style intro consideration

Workaround (if any):
Given that this style is already present for SkinnableContainer it should work out of the box.

The workaround consists in duplicating the default skin and change:

<s:Rect id="backgroundRect" left="0" right="0" top="0" bottom="0" >
<s:fill>
<!--- @private -->
<s:SolidColor id="bgRectFill" color="#FFFFFF"/>
</s:fill>
</s:Rect>

for

<s:Rect id="backgroundRect" left="0" right="0" top="0" bottom="0" >
<s:fill>
<!--- @private -->
<s:SolidColor id="bgRectFill" color="#FFFFFF" alpha="X"/>
</s:fill>
</s:Rect>

I'd expect the framework to directly tight the style value
