  12. abstract def winBufSize: Int

    The size for the window buffer, or zero if this buffer should no be used.

    The size for the window buffer, or zero if this buffer should no be used. This can be polled multiple times per window, the element might thus need to be saved (in tryObtainWinParams()). In most cases, it will be sufficient to poll the value in tryObtainWinParams and implement winBufSize by calling the value method of the corresponding input handler.
