=head1 NAME
Imager::Font::Truetype - low-level functions for Truetype fonts
=head1 DESCRIPTION
Imager::Font creates a Imager::Font::Truetype object when asked to
create a font object based on a F<.ttf> file.
See Imager::Font to see how to use this type.
This class provides low-level functions that require the caller to
perform data validation.
