By default, spawn location is randomly selected from within the spawning area defined by SpawnRange or X1Y1 X2Y2.
By adding one of the following control keywords to the beginning of the entry, several different positioning methods can be used.
#XFILL[,inc] will add spawns by filling the spawn area progressively in rows of X.
#YFILL[,inc] will add spawns by filling the spawn area in rows of Y.
#EDGE[,inc] will add spawns only around the edge of the spawn area.
These can be used to systematically fill spawning areas, when random positioning is not desired.
An additional optional increment value can be passed as an argument to these keywords to change the spacing between successive spawn positions.
#PLAYER[,range] - places the spawns around the triggering player.
#WAYPOINT,prefix[,range] - places the spawn at the location of randomly selected waypoint runes that start with the given prefix.
spawn the specified statics only around the perimeter of the spawing area.
