parent 3fd39feb4153cf73f26223918bc8145ee98a9a92
Author: Anselm R. Garbe <garbeam@gmail.com>
Date:   Sun, 28 Oct 2007 12:41:14 +0100

replaced ISTILE with domwfact/dozoom bools, removed nrules, nlayouts and ltidx, added NRULES, NLAYOUTS and Layout *layout as alternatives, removed isarrange(), checking against layout->arrange instead.
