#   opacity:::

#   focus:::

#   full-shadow:::
#     Controls whether shadow is drawn under the parts of the window that you

#     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,
