- removed ugly clamping function (it was dividing XYZ based on max of one of the values) - added option to use Exposure, this only works for brightness (Y). results look very pleasant, foggy and hazy results are possible. with exposre==0, no exposure happens for HDR extreme range skies, this is how yafray rendered it. - added menu for choosing color spaces (CIE = modern lcds) Please review! (and yes i know it's still not in World :)
