/**
* Compute a scale factor to limit the precision of
* a given combination of Geometry and buffer distance.
* The scale factor is determined by
* the number of digits of precision in the (geometry + buffer distance),
* limited by the supplied <code>maxPrecisionDigits</code> value.
* <p>
* The scale factor is based on the absolute magnitude of the (geometry + buffer distance).
* since this determines the number of digits of precision which must be handled.
*
* @param g the Geometry being buffered
* @param distance the buffer distance
* @param maxPrecisionDigits the max # of digits that should be allowed by
* the precision determined by the computed scale factor
* @return a scale factor for the buffer computation
