ASButtonNode Edit on GitHub

ASButtonNode (a subclass of ASControlNode) supports simple buttons, with multiple states for a text label and an image with a few different layout options. Enables layerBacking for subnodes to significantly lighten main thread impact relative to UIButton (though async preparation is the bigger win).

Features: - supports state-changing background images - supports state-changing titles - supports text alignment - supports contentEdgeInsets - offers methods that allow more convenient usage than creating attributed strings — title NSString, UIFont, and UIColor.

Gotchas: - the selected property logic should be handled by the developer. Tapping the ASButtonNode does not automatically enable selected.
