 * `Triangle.type` is a new property containing the shapes geometry type, which can be used for quick type comparisons.
 * `InputPlugin.enableDebug` is a new method that will create a debug shape for the given Game Objects hit area. This allows you to quickly check the size and placement of an input hit area. You can customzie the shape outline color. The debug shape will automatically track the Game Object to which it is bound.
 * `InputPlugion.removeDebug` will remove a Debug Input Shape from the given Game Object and destroy it.
+* `Pointer.updateWorldPoint` is a new method that takes a Camera and then updates the Pointers `worldX` and `worldY` values based on the cameras transform (thanks @Nick-lab)
