=head1 NAME

Game::TextMapper::Point::Square - a square on a map

=head1 SYNOPSIS

    use Modern::Perl;
    use Game::TextMapper::Point::Square;
    my $square = Game::TextMapper::Point::Square->new(x => 1, y => 1, z => 0);
    say $square->svg_region('', [0]);
    #

=head1 DESCRIPTION

This class holds information about a square region: coordinates, a label, and
types. Types are the kinds of symbols that can be found in the region: a keep, a
tree, a mountain. They correspond to SVG definitions. The class knows how to
draw a SVG rectangle at the correct coordinates using these definitions.

=head1 SEE ALSO

This is a specialisation of L.

The SVG size is determined by C<$dy> from L.
