Finally implemented perceptual brightness thing.

function u=construct(s,sizes_in)
	figure(fig(s));

	xl=s.opts.xlim;
	yl=s.opts.ylim;
	X=zeros(sizes_in{1}); 

	if isempty(xl) && isempty(yl)
		h=image(X,s.opts.args{:});
	else
		if isempty(xl) xl=[1,size(X,2)]; end
		if isempty(yl) yl=[1,size(X,1)]; end
		h=image(xl,yl,X,s.opts.args{:});
	end
	if isfield(s.opts,'ylabel'), ylabel(s.opts.ylabel); end
	if isfield(s.opts,'xlabel'), xlabel(s.opts.xlabel); end

	u=mkunit(s);
	if autoflush(s), u.process =@proc_flush;
	else u.process=@proc_noflush; end

	u.sizes_out = {};
	u.dispose = @()delete(h);

	function proc_flush(x), set(h,'CData',x); drawnow; end
	function proc_noflush(x), set(h,'CData',x); end
end
