-=head1 NAME
-
-Font::TTF::Dumper - Debug dump of a font datastructure, avoiding recursion on ' PARENT'
-
-=head1 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");
-
-=head1 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.)
