function target = transfer(this,axisHandle,varargin)
%KML.TRANSFER(ax) Transfer the axis from the handle ax to the KML as an overlay.
% Example:
% k = kml;
% t = linspace(0,2*pi,1000);
% figure;
% plot(t,sin(t));
% k.transfer(gca)
% k.run
%
% The corners of the overlay are taken from the axis limits.
