The pool would be refilled when the compositor starts rendering the frame. However, if we consume lots of textures but doesn't render any frame, then the pool would always empty and no one can get new texture id. One case is that when we release decoders too early before rendering the first frame, the pool won't be refilled, and it causes all media threads are blocked. Now we would refill the pool if the textures number is lower than the specific threshold. MozReview-Commit-ID: CYBLYi9hFD9
