=head1 NAME
Graphics::Primitive::Border - Line around components
=head1 DESCRIPTION
Graphics::Primitive::Border describes the border to be rendered around a
component.
=head1 SYNOPSIS
use Graphics::Primitive::Border;
my $border = Graphics::Primitive::Border->new;
=head1 METHODS
=head2 new
Creates a new Graphics::Primitiver::Border. Borders are composed of 4
brushes, one for each of the 4 sides. See the documentation for
L<Graphics::Primitive::Brush> for more information. Note that you can
provide a C<width> and C<color> argument to the constructor and it will create
brushes of that width for each side.
=head2 bottom
The brush representing the bottom border.
=head2 clone
Close this border.
=head2 color
Set the Color on all 4 borders to the one supplied. Shortcut for setting it
with each side.
=head2 dash_pattern
Set the dash pattern on all 4 borders to the one supplied. Shortcut for
setting it with each side.
=head2 equal_to ($other)
Returns 1 if this border is equal to the one provided, else returns 0.
=head2 homogeneous
Returns 1 if all of this border's sides are the same. Allows for driver
optimizations.
=head2 left
The brush representing the left border.
=head2 not_equal_to
Opposite of C<equal_to>.
=head2 right
The brush representing the right border.
=head2 top
The brush representing the top border.
=head2 width
Set the width on all 4 borders to the one supplied. Shortcut for setting it
with each side.
