# opacity:::

# 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

# set, and doesn't want certain window to cause unnecessary screen redirection,
# you can set this to `true`.
