[Xmonad] darcs patch: An alternative mosaic layout implementation

This is a new layout which is very similar to David's Mosaic, but produces different tilings. The algorithm is simpler, but I think it gives more useful results. It divides the space in a more balanced way, in particular trying to avoid very narrow windows. Cheers /J Tue Oct 2 02:17:16 BST 2007 Jamie Webb * An alternative mosaic layout implementation
