Finally implemented perceptual brightness thing.

% minmax - minmax for sequences operates over ENTIRE sequence
%
% minmax :: [D:[[1,E]]], I:[E] -> [set(D,I,2)].
%
% If you want minmax on a per-buffer basis, use fnseq:
%  R=fnseq(@(x)minmax(x,dim),X)
function R=minmax(X,dim)
	R=foldl(@(r,t)minmax(cat(dim,r,t),dim),[],X);
end
