/* ALL THIS IS DUMMY IMPLEMENTATION
   FOR TEST PURPOSE ONLY
	
I'm far to be an xml designer or however it has to be called, so I present the xml/ufr format quite simply (no schema inside).

<font name="foo" path="bar">
	<glyph codepoint="XXXX" />
	.
	.
	.
	.
</font>
... to say that you can have as many font elements as you want and other ones will come asap !
