Override backgroundColor of ScrollPane

[Edvin Syse]

In some cases I want to change the backgroundColor of a ScrollPane. I do 
it like this:

        ScrollPaneSkin skin = (ScrollPaneSkin) getSkin();
        TerraTheme theme = (TerraTheme) Theme.getTheme();
        skin.setBackgroundColor(theme.getColor(10));
I don't care that I reference the TerraTheme directly, but apart from 
that - is this a good way to do it?
