+====== Decoration (DED) ======
+Light decorations for surfaces.
+You can define multiple Decorations for the same texture/flat, but only the
+latest one that passes the conditions will be used. By default (if you
+specify no usage flags), a Decoration is only used with resources loaded
+from an IWAD.
+Note that [[Material]] definitions can be used to define light decorations, as well.
+===== Syntax =====
+  <Copy> Decoration
+  {
+    # If "Copy" is found all the data of the previous definition is
+    # copied to this one as defaults. For the first definition in a
+    # file "Copy" has no effect.
+    Texture = ""
+    # Name of the texture with which this decoration is used.
+    Flat = ""
+    # Name of the flat with which this decoration is used. You can
+    # only specify either a Texture or a Flat, not both.
+    Flags = flaga | flagb | flagc etc...
+    # noiwad: Don't use this decoration if the resource is loaded from an IWAD.
+    # pwad: This decoration can be used with PWAD resources (for example custom textures).
+    # ext: This decoration can be used with external resources.
+      Light
+      {
+        # Each decoration can specify up to 16 lights.
+        Offset { 0.0 0.0 }
+        # Origin of the light in texture coordinates.
+        Distance = 1.0
+        # Distance between the origin of the light and the surface.
+        Color { 0.0 0.0 0.0 }
+        # RGB color (values 0-1) of the light. Color (0,0,0) marks
+        # the end of the light definitions. Any lights that follow are
+        # not rendered.
+        Radius = 1.0
+        # Radius of the dynamic light.
+        Halo radius = 0.0
+        # Radius of the halo. Zero means no halo is rendered. Note
+        # that halo radius 1.0 produces quite a large flare.
+        Flare map = ""
+        # Name of the flare map to use OR a built-in flare texture id to use for the primary flare (i.e. the halo itself).
+        # Eg:
+        # Flare map = "myflaremap.png" (loaded from the data/<game>/flaremaps folder by default).
+        # Flare map = "1"
+        # Built-in flare texture ids:
+        # 0 = Texture chosen automatically.
+        # 1 = Default dynamic light texture.
+        # 2 = FLARE.
+        # 3 = BRFLARE.
+        # 4 = BIGFLARE.
+        Flare texture = 0
+        # DEPRECATED:
+        # This parameter has been replaced with "Flare map" as of 1.9.0-beta4.
+        Top map = ""
+        Bottom map = ""
+        Side map = ""
+        # Name of the light map to use. The top map is used for ceiling
+        # planes, the bottom map for floors and the side map for walls.
+        # If left blank (the default), the standard round dynlight
+        # texture is used. Use "-" to disable a map entirely. No light
+        # will then be cast in the direction.
+        Levels { 0 0 }
+        # Two integers (0-255) that mark the sector light levels where
+        # the light is at zero and maximum brightness, respectively.
+        # For example, the levels { 100 200 } mean that the light is
+        # not visible under light level 100, fades gradually to full
+        # brightness when nearing light level 200, and stays full
+        # bright over 200. The first level can be higher than the
+        # second. The behaviour is then reversed: the light is at full
+        # brightness only below the lower light level.
+        Pattern skip { 0 0 }
+        # Normally the light is repeated on a surface as many times as
+        # the texture or flat repeats. The pattern skip values allow
+        # sparser repeats for horizontal and vertical patterns,
+        # respectively. For example, the skips { 1 2 } will make the
+        # light only appear on every second horizontal repeat and
+        # every third vertical repeat.
+        Pattern offset { 0 0 }
+        # Used with pattern skip to offset the origin of the pattern.
+        # For example, the offset { 1 0 } will shift the origin of the
+        # pattern one full horizontal repeat.
+      }
