+#     "tooltip", "notification", "combo", and "dnd".
+# 
+# Following per window-type options are available: ::
+# 
+#   fade, shadow:::
+#     Controls window-type-specific shadow and fade settings.
+# 
+#   opacity:::
+#     Controls default opacity of the window type.
+# 
+#   focus:::
+#     Controls whether the window of this type is to be always considered focused. 
+#     (By default, all window types except "normal" and "dialog" has this on.)
+# 
+#   full-shadow:::
+#     Controls whether shadow is drawn under the parts of the window that you 
+#     normally won't be able to see. Useful when the window has parts of it 
+#     transparent, and you want shadows in those areas.
+# 
+#   redir-ignore:::
+#     Controls whether this type of windows should cause screen to become 
+#     redirected again after been unredirected. If you have unredir-if-possible
+#     set, and doesn't want certain window to cause unnecessary screen redirection, 
+#     you can set this to `true`.
