/** {@link AssetLoader} for {@link Skin} instances. All {@link Texture} and {@link BitmapFont} instances will be loaded as
 * dependencies. Passing a {@link SkinParameter} allows the exact name of the texture associated with the skin to be specified.
 * Otherwise the skin texture is looked up just as with a call to {@link Skin#Skin(com.badlogic.gdx.files.FileHandle)}. A
 * {@link SkinParameter} also allows named resources to be set that will be added to the skin before loading the json file,
 * meaning that they can be referenced from inside the json file itself. This is useful for dynamic resources such as a BitmapFont
 * generated through FreeTypeFontGenerator.
