=head1 NAME
Graphics::Primitive::Paint::Gradient::Linear - Linear color blending
=head1 DESCRIPTION
Graphics::Primitive::Paint::Gradient::Linear is a gradient along a line.
=head1 SYNOPSIS
use Graphics::Primitive::Paint::Gradient::Linear;
my $gradient = Graphics::Primitive::Gradient::Linear->new(
line => Geometry::Primitive::Line->new(
start => Graphics::Primitive::Point->new(x => 0, y => 0),
end => Graphics::Primitive::Point->new(x => 0, y => 10),
)
);
$gradient->add_stop(0.0, $color1);
$gradient->add_stop(1.0, $color2);
=head1 METHODS

=item I<line>
The line along which the gradient should run.
=item I<stop_count>
Count of stops added to this Gradient.
