=head1 NAME

Font::TTF::Fpgm - Font program in a TrueType font. Called when a font is loaded

=head1 DESCRIPTION

This is a minimal class adding nothing beyond a table, but is a repository

for fpgm type information for those processes brave enough to address hinting.

use strict;

use vars qw(@ISA $VERSION);

@ISA = qw(Font::TTF::Table);

$VERSION = 0.0001;

=head2 $t->read

Reading this table is simply a process of reading all the data into the RAM

copy. Nothing more is done with it.

    $_[0]->{' read'} = 1;

}

=head2 $t->out_xml($context, $depth)

Outputs Fpgm program as XML
