	 *  The version of this method without an explicit length argument calls glGetBufferParameter internally to
	 *  retrieve the current buffer object size, which may cause a pipeline flush and reduce application performance.
	 *  <p/>
	 *  The version of this method with an explicit length argument is a fast alternative to the one without. No GL call
	 *  is made to retrieve the buffer object size, so the user is responsible for tracking and using the appropriate length.<br>
