 *  This should only be thrown when the library tries to write to a buffer
 *  e.g when the position is greater than the position and the stream
 *  is not set to autoresize.<br />
 *  <br />
 *  It is <b>NOT</b> appropriate to use <b>throw new</b> so avoid doing so,
 *  keeping things on the stack as much as possible is very important for speed.
