Transform::computeScalingRotation flush determinant to +/- 1.

In the previous code, in attempting to correct for a negative
determinant, we end up multiplying and dividing by a number that
is often very near, but not exactly +/-1.  By flushing to +/-1,
we can replace a division with a multiplication, and results
are more numerically consistent.
