// returned by CreateFrame(). When one of these VideoFrames is destroyed,
// the memory is returned to the pool for use by a subsequent CreateFrame()
// call. The memory in the pool is retained for the life of the
// VideoFramePool object. If the parameters passed to CreateFrame() change
// during the life of this object, then the memory used by frames with the old
// parameter values will be purged from the pool.
