New skinning in FX8 – where do the style classes go

The new SkinBase is returning a modifiable version of the control's 
children. The FX2 way was actually more convoluted with 
behind-the-scenes copying of properties but I think that is covered on 
the wiki.

This works for me. Maybe your css selectors need to be adjusted. After 
all the node hierarchy no longer has an extra skin node.

Certainly not.

In my opinion the control creation process is quite simple now. Create a 
new control class, set the style class, and provide the default skin by 
overriding createDefaultSkin(). Here you return an instance of your skin 
which extends SkinBase. Which is where you observe the control 
properties as usual. And use SkinBase.getChildren to add skin content.
