# tests on nouveau show terrible slowdown.

## Window type settings

    #   https://specifications.freedesktop.org/wm-spec/latest/ar01s05.html#idm45550357242464
    # fade: Fade the particular type of windows.
    # shadow: Give those windows shadow
    # opacity: Default opacity for the type of windows.
    # 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.
