+--com.bumpslide.ui.HorizontalScrollPanelHorizontal Scroll Panel Base Class This is a simple extension of the scroll panel that supports horizontal scrolling. The trick here is to create a vertical scroll panel, and then rotate it -90 on the stage. Then, the content is attach at 90 degrees to compensate. The weird part, then is that a lot of the dimensions (height and width) are backwards in the update function. This class takes care of that messiness. TODO: Make scrollbar work natively in a horizontal mode so we don't have to deal with this.
