vtkImageAccumulate doesn't seem to work for doubles, so need custom method for calculating pixel value ranges.

Performs a linear mapping of floating point image values to 16 bit integer dynamic range. Returns a signed short array, together with the intercept and slope of the linear scaling transformation ( shortVal = floatVal * slope + intercept).
