The addImageAsync logic follow the steps:

_responseQueue (Load thread)
- on schedule callback, get AsyncStruct from _responseQueue, convert image to texture, then delete AsyncStruct (GL

the Critical Area include these members:
- _requestQueue: locked by _requestMutex
- _responseQueue: locked by _responseMutex
the object's life time:
- AsyncStruct: construct and destruct in GL thread
- image data: new in Load thread, delete in GL thread(by Image instance)
Note:
- all AsyncStruct referenced in _asyncStructQueue, for unbind function use.
How to deal add image many times?
- At first, this situation is abnormal, we only ensure the logic is correct.
- If the image has been loaded, the after load image call will return immediately.
- If the image request is in queue already, there will be more than one request in queue,
- In addImageAsyncCallback, will deduplicate the request to ensure only create one texture.
Does process all response in addImageAsyncCallback consume more time?
- Convert image to texture faster than load image from disk, so this isn't a
problem.
Call unbindImageAsync(path) to prevent the call to the callback when the
texture is loaded.

The callbackKey allows to unbind the callback in cases where the loading of

unbind the callback independently as needed whilst a call to
unbindImageAsync(path) would be ambiguous.
