Title : Wish StarlingTextureLoader can be instantiated with starling Textures.

Using Spine runtime for Starling, we can make SkeletonData with general starling TextureAtlas by StarlingAtlasAttachmentLoader.
Also we can make SkeletonData with Spine TextureAtlas by StarlingTextureLoader with AtlasAttachmentLoader (like your GoblinsExample).

Here, there is a problem.

StarlingAtlasAttachmentLoader requires Bitmap(s) or BitmapData(s) for instantiation.
It is common that Starling users load image assets via starling.utils.AssetsManager, but AssetsManager automatically makes starling.textures.Texture from BitmapData loaded and remove the BitmapData immediately. We can never get BitmapDatas from AssetsManager.

That means, when we load Spine TextureAtlas files via AssetsManager, it is impossible to make SkeletonDatas.

To solve this problem, I made custom StarlingTextureLoader.

Hope Spine runtime for Starling has this feature officially. :hi:

Updated.

This works with Starling2 and Spine3.4 Runtime...
