	Just mucking around with some fake scattering. 
	Trying to come up with a nice-looking raymarched solution for atmospheric 
	scattering out to the edge of the atmosphere, plus a fast non-iterative version
	for nearer the viewer.

	Some code pinched from here: http://glsl.heroku.com/e#17563.3
	and here: http://codeflow.org/entries/2011/apr/13/advanced-webgl-part-2-sky-rendering/

function [maxtab, mintab]=peakdet(v, delta, x)
%PEAKDET Detect peaks in a vector
%        [MAXTAB, MINTAB] = PEAKDET(V, DELTA) finds the local
%        maxima and minima ("peaks") in the vector V.
%        MAXTAB and MINTAB consists of two columns. Column 1
%        contains indices in V, and column 2 the found values.
%      
%        With [MAXTAB, MINTAB] = PEAKDET(V, DELTA, X) the indices
%        in MAXTAB and MINTAB are replaced with the corresponding
%        X-values.
