/*
 * FORMAT TEMPLATE RULES
 *
 * Authors :
 *   Almer S. Tigelaar <almer1@dds.nl>
 *   Jody Goldberg <jody@gnome.org>
 *
 * ----------------------------------------------------------------------------
 * Placement :
 *   offset :
 *     1. These can only be positive and indicate the number of
 *        columns from the side (see gravity)
 *   offset_gravity :
 *     1. This is the side to count offset from,
 *        gravity (for rows : +1=top, -1=bottom; for cols : +1=left, -1=right).
 *
 * Dimensions :
 *   size :
 *     1. The number of cols/rows from the offset, if this is <=0 than this is
 *        relative to the 'far side' otherwise it is relative to the offset.
 *
 * Frequency :
 *   direction :
 *     1. The direction to repeat in, this can be either horizontal
 *        or vertical.
 *   repeat :
 *     1. When repeat >= 0, we will repeat
 *        repeat times, if it is something else (preferably -1) we
 *        simply repeat _indefinitely_ in vertical or horizontal directions.
 *   skip :
 *     1. When skip is 0 or smaller than 0 we don't skip
 *        any rows or cols in between applications.
 *   edge :
 *     1. Can be 0 or greater. Specifies the number of rows to at least
 *        not but a repetetive style calculated from the far side.
 * ----------------
