+ * tilecols[] array which is used by tile(), and a Column maxcols[] arrays which is used by
+ * maximise(). Those arrays should be initialized in config.h. For simplicity
+ * reasons mwfact should be replaced with a more advanced method which

+ * tilecols[1] instead. Besides this, get rid of BARPOS and use instead the
