    Another attempt to fix bug 691629.
    
    To solve bug 691629 we need to ensure that the scaling weights for
    every pixel in a gridfitted image sum to 256. I had attempted to
    do that by enabling the 'WRAP' code, but this has the effect of
    adding too much bias to the outlying source pixels, resulting in
    thickened serifs etc.
    
    A better fix is to extend the code that is already present to check
    the weights for validity. If an image pixel is completely covered,
    then force the weights to 256 by adjusting the largest weight.
    
    This still skews the output slightly but it's a much less visible
    result.
