/**
The addImageAsync logic follow the steps:
- find the image has been add or not, if not add an AsyncStruct to _requestQueue (GL thread)
- get AsyncStruct from _requestQueue, load res and fill image data to AsyncStruct.image, then add AsyncStruct to _responseQueue (Load thread)
- on schedule callback, get AsyncStruct from _responseQueue, convert image to texture, then delete AsyncStruct (GL thread)
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.
