The way it works is like this: First call id3_tag_render() with a null 
buffer argument. It will return the maximum possible size of the 
rendered tag (without actually rendering yet). Then allocate your 
buffer using this size and pass it to the routine again, and this time 
the tag will be rendered in your buffer and the actual size returned. 
The actual size may be smaller than the original estimate, but it will 
never be larger.
