NAME
       Font::TTF::Dumper - Debug dump of a font datastructure, avoiding recursion on ' PARENT'

SYNOPSIS
	   Font::TTF::Dumper;

	   # Print a table from the font structure:
	   print ttfdump($font->{$tag});

	   # Print font table with name
	   print ttfdump($font->{'head'}, 'head');

	   # Print one glyph's data:
	   print ttfdump($font->{'loca'}->read->{'glyphs'}[$gid], "glyph_$gid");

DESCRIPTION
       Font::TTF data structures are trees created from hashes and arrays. When trying to figure out how the structures work, sometimes it is
       helpful to use Data::Dumper on them. However, many of the object structures have ' PARENT' links that refer back to the object's parent,
       which means that Data::Dumper ends up dumping the whole font no matter what.

       The purpose of this module is to do just one thing: invoke Data::Dumper with a filter that skips over the ' PARENT' element of any hash.

       To reduce output further, this module also skips over ' CACHE' elements and any hash element whose value is a Font::TTF::Glyph or
       Font::TTF::Font object.	(Really should make this configurable.)
