This slot can be reimplemented by the decoration to return the regions defined by KDecorationDefines::Region. The only region defined initially is ExtendedBorderRegion. This region specifies an invisible input region that can extend both inside and outside the decoration. The intended use case is to be able to have an active border area that's larger than the visible borders.
