=head1 NAME
Geometry::Primitive::Bezier - Cubic Bézier Curve
=head1 DESCRIPTION
Geometry::Primitive::Bezier represents a cubic Bézier curve.
=head1 SYNOPSIS
use Geometry::Primitive::Bezier;
my $line = Geometry::Primitive::Bezier->new(
start => $point1,
control1 => $point2,
control2 => $point3,
end => $point4
);
=head1 ATTRIBUTES
=head2 control1
Set/Get the first control point of the curve.
=head2 control2
Set/Get the second control point of the curve.
=head2 end
Set/Get the end point of the curve.
=head2 start
Set/Get the start point of the line.
=head1 METHODS
=head2 new
Creates a new Geometry::Primitive::Bezier
=head2 grow
Does nothing, as I'm not sure how. Patches or hints welcome.
=head2 point_end
Get the end point. Provided for Shape role.
=head2 point_start
Get the start point. Provided for Shape role.
=head2 scale
Scales this curve by the amount provided. Multiplies each coordinate by the
amount.
=head2 to_string
Guess!
