+//generic (by snowflake) tile smoothing code; smooth your icons with this!
+/*
+	Each tile is divided in 4 corners, each corner has an image associated to it; the tile is then overlayed by these 4 images
+	To use this, just set your atom's 'smooth' var to 1. If your atom can be moved/unanchored, set its 'can_be_unanchored' var to 1.
+	If you don't want your atom's icon to smooth with anything but atoms of the same type, set the list 'canSmoothWith' to null;
+	Otherwise, put all types you want the atom icon to smooth with in 'canSmoothWith' INCLUDING THE TYPE OF THE ATOM ITSELF.
+
+	Each atom has its own icon file with all the possible corner states. See 'smooth_wall.dmi' for a template.
+
+	DIAGONAL SMOOTHING INSTRUCTIONS
+	To make your atom smooth diagonally you need all the proper icon states (see 'smooth_wall.dmi' for a template) and
+	to add the 'SMOOTH_DIAGONAL' flag to the atom's smooth var (in addition to either SMOOTH_TRUE or SMOOTH_MORE).
+
+	For turfs, what appears under the diagonal corners depends on the turf that was in the same position previously: if you make a wall on
+	a plating floor, you will see plating under the diagonal wall corner, if it was space, you will see space.
+
+	If you wish to map a diagonal wall corner with a fixed underlay, you must configure the turf's 'fixed_underlay' list var, like so:
+		fixed_underlay = list("icon"='icon_file.dmi', "icon_state"="iconstatename")
+	A non null 'fixed_underlay' list var will skip copying the previous turf appearance and always use the list. If the list is
+	not set properly, the underlay will default to regular floor plating.
+
+	To see an example of a diagonal wall, see '/turf/simulated/wall/shuttle' and its subtypes.
