	 * glMapBuffer maps a gl vertex buffer buffer to a ByteBuffer. The oldBuffer argument can be

	 * oldBuffer is non-null, it will be returned if it points to the same mapped memory, otherwise a
	 * new ByteBuffer is created. That way, an application will normally use glMapBuffer like this:
	 * <p/>
	 * ByteBuffer mapped_buffer; mapped_buffer = glMapBuffer(..., ..., ..., null); ... // Another
	 * map on the same buffer mapped_buffer = glMapBuffer(..., ..., ..., mapped_buffer);
	 *
	 * @param size      The size of the buffer area.
	 * @param oldBuffer A ByteBuffer. If this argument points to the same address as the new mapping,
	 *                  it will be returned and no new buffer will be created. In that case, size is
	 *                  ignored.
	 *
	 * @return A ByteBuffer representing the mapped buffer memory.
