 * If you load an image and provide a key that was already in-use in the Cache, then the old image is now destroyed (via `Cache.removeImage`) and the new image takes its place.
 * BitmapText has a new `maxWidth` property that will attempt to wrap the text if it exceeds the width specified.
 * Group.cursorIndex is the index of the item the Group cursor points to. This replaces Group._cache[8].
-* Stage.visibilityChange now has a second parameter `fromPhaser`. This is set to `true` by the `Stage._onChange` callback. This should mean that when Phaser is listening for `window.onblur` and `window.onfocus` events it will only trigger the visibilityChange if that event was generated by Phaser itself. If it was generated by something else on the page or iframe it should now be ignored (thanks @austinhallock #1620)
