 # Usage
 
 In the main thread somewhere at the start of the project need to call `ImageLoader.Init();` once to initialize static properties in the right thread. It is required to make in the main thread. Then you can use `ImageLoader` from any thread and at any time.

 # Texture Memory Management
 
 ImageLoader can manager memory usage of loaded textures. To use it need to call `ImageLoader.LoadSpriteRef` instead of `ImageLoader.LoadSprite`. It will return `Reference<Sprite>` object which contains `Sprite` and `Url` objects. When `Reference<Sprite>` object is not needed anymore, call `Dispose` method to release memory, or just don't save the reference on it. It is `IDisposable` and it will clean itself automatically. Each new instance of `Reference<Sprite>` increments reference counter of the texture. When the last reference is disposed, the texture will be unloaded from memory. Also the all related References will be automatically disposed if you call `ImageLoader.ClearMemoryCache` or `ImageLoader.ClearCache`.
