// Resource loading is not yet thread safe. If an animation is not loaded when requested by other than tha main thread,
// we block in AnimationHandle::setURL => AnimationCache::getAnimation.
// Meanwhile, the main thread will also eventually lock as it tries to render us.
// If we demand the animation from the update thread while we're locked, we'll deadlock.
// Until we untangle this, code puts the updates back on the main thread temporarilly and starts all the loading.
