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

SYNOPSIS
        use 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 font table with name and other options
        print ttfdump($font->{'head'}, 'head', %opts);

        # 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 main purpose of this module is to 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.)

    If $opts{'d'}, then set Deepcopy mode to minimize use of crossreferencing.
