    Whether the shade layout should be full width (true) or floating (false).

    In a floating layout, notifications and quick settings each take up only up to half the screen
    width (whether they are shown at the same time or not). In a full width layout, they can each be
    as wide as the entire screen.

    Whether notifications shade should be in the top end position (e.g. the right side of the screen
    in an LTR locale) on wide screens.
    Only used in Dual Shade mode, when `config_isFullWidthShade` is `false`. Ignored in all other
    cases.

    Sets the boundary for the swipe-down gesture from the top of the screen that opens the
    Notifications and Quick Settings shades in Dual Shade mode.

    This value is a ratio (from 0.0 to 1.0) that represents the fraction of the screen width
    dedicated to notifications, measured from the "start" edge (left in LTR layouts, right in RTL).

     - Swiping from the start edge to this boundary opens Notifications.
     - Swiping from this boundary to the end edge opens Quick Settings.
