    Do the test filtering in the existing backup frame buffer instead of
    the original. Copy the original data into extra buffer before doing
    the  filtering. This way there is no need to restore the original
    unfiltered  frame at the end of level picking process.
    This came up in some discussions with Johann. Thanks!
