    median-blur: rename "exact" prop to "high-precision"
    
    This property has no effect for R'G'B'/Y' u8 inputs, since
    quantization doesn't introduce any error in these cases.  The new
    name will hopefully make this fact less surprising.
    
    In the future, it would be nice if we could use GUM to control the
    visibility of properties based on the input format.
