/**
* The <i>Padding Object</i> is a dummy object that is used to pad the size of
* the <i>Header Object</i>. This object enables the size of any object stored
* in the <i>Header Object</i> to grow or shrink without having to rewrite the
* entire <i>Data Object</i> and <i>Index Object</i> sections of the ASF file.
* For instance, if entries in the <i>Content Description Object</i> or
* <i>Extended Content Description Object</i> need to be removed or shortened,
* the size of the <i>Padding Object</i> can be increased to compensate for the
* reduction in size of the <i>Content Description Object</i>. The ASF file can
* then be updated by overwriting the previous <i>Header Object</i> with the
* edited <i>Header Object</i> of identical size, without having to move or
* rewrite the data contained in the <i>Data Object</i>.
