=head1 NAME

Imager::Font::W32 - font support using C<GDI> on Win32

=head1 SYNOPSIS

  use Imager;

  my $img = Imager->new;
  my $font = Imager::Font->new(face => "Arial", type => "w32");

  $img->string(... font => $font);

=head1 DESCRIPTION

This provides font support on Win32.

=head1 CAVEATS

Unfortunately, older versions of Imager would install
Imager::Font::Win32 even if Win32 wasn't available, and if no font was
created would succeed in loading the module.  This means that an
existing Win32.pm could cause a probe success for Win32 fonts, so I've
renamed it.
