=head1 NAME

Box2D::b2RayCastOutput - Ray-cast output data.

=head1 SYNOPSIS

  my $output = Box2D::b2RayCastOutput->new();
  $shape->RayCast( $output, $input, $transform );
  my $fraction = $output->fraction();
  my $normal   = $output->normal();

=head1 DESCRIPTION

Ray-cast output data. The ray hits at S<p1 + fraction * (p2 - p1)>,
where p1 and p2 come from C<Box2D::b2RayCastInput>.
