Groups have a new method `alignIn`. It allows you to align the Group within another Game Object, or a Rectangle. You can specify one of 9 positions which are the new position constants such as: `Phaser.TOP_LEFT` or `Phaser.CENTER` (see docs for the complete list). The Groups are positioned based on their child bounds, which takes rotation and scaling into consideration. You can easily place Groups into the corners of the screen, or game world, or align them within other Sprites, using this method.
Groups have a new method `alignTo`. It allows you to align a Group to the side of another Game Object, or a Rectangle. You can specify one of 11 positions which are the new position constants such as: `Phaser.TOP_LEFT` or `Phaser.LEFT_BOTTOM` (see docs for the complete list). The Groups are positioned based on their child bounds, which takes rotation and scaling into consideration. You can easily align Groups next to other Sprites using this method.
* The PIXI.BaseTexture.imageUrl property has been removed, as it was never actually populated.
* The PIXI.BaseTexture._UID property has been removed, as it was never actually used internally.
* All references to PIXI.BaseTextureCache have been removed (primarily from BaseTexture.destroy and Texture.destroy), as the BaseTextureCache was never used internally by Phaser, or by our custom version of Pixi.
* PIXI.TextureCache has been removed. It was only ever used by the __default and __missing images that Phaser generates on start-up. It wasn't used internally by Phaser anywhere else, and the only references Pixi has to it have all been removed. If you need it in your own game, please refactor it to avoid it, or re-create the object on the PIXI global object.
* Canvases created by `BaseTexture.fromCanvas` no longer have the `_pixiId` property attached to them, as this was never used internally by Phaser or Pixi.
* PIXI.BaseTexture.updateSourceImage is now deprecated. Please use `Sprite.loadTexture` instead.
* The property PIXI.BaseTextureCacheIdGenerator has been removed, as it is no longer used internally by Phaser or Pixi.
* PIXI.Texture.addTextureToCache has been removed. The PIXI Texture Cache was never actually used by Phaser, and was leading to complications internally.
* PIXI.Texture.removeTextureFromCache has been removed. The PIXI Texture Cache was never actually used by Phaser, and was leading to complications internally.
* PIXI.Texture.fromFrame and PIXI.Sprite.fromFrame have been removed. They relied on the PIXI Texture Cache, which was never actually used by Phaser, and was never used internally by Pixi either.
* The property PIXI.TextureCacheIdGenerator has been removed, as it was not used internally.
* The property PIXI.FrameCache has been removed, as it was not used internally.
BitmapData.copyTransform allows you to draw a Game Object to the BitmapData, using its `worldTransform` property to control the location, scaling and rotation of the object. You can optionally provide
BitmapData.drawGroup now uses the new `copyTransform` method, to provide for far more accurate results. Previously nested Game Objects wouldn't render correctly, nor would Sprites added via `addChild` to another Sprite. BitmapText objects also rendered without rotation taken into account, and the Sprites smoothing property was ignored. All of these things are now covered by the new drawGroup method, which also handles full deep iteration down the display list.
When using a style on characters (e.g. addColor), the length of the whole line with default style was measured ignoring the different width of the characters with added style.
I've included the measureLine function, which does the same measurements as updateLine, but it does not render the line to canvas - it only returns the line length.
Now this function is used for measuring line of text if some style is added to it.
