+ *	   = 2^2n u1 v1  +     2^n (u1 v0 + v1 u0)   +  u0 v0
+ *
+ * Now add 2^n u1 v1 to the first term and subtract it from the middle,
+ * and add 2^n u0 v0 to the last term and subtract it from the middle.
+ * This gives:
+ *
+ *	uv = (2^2n + 2^n) (u1 v1)  +
+ *	         (2^n)    (u1 v0 - u1 v1 + u0 v1 - u0 v0)  +
+ *	       (2^n + 1)  (u0 v0)
+ *
+ * Factoring the middle a bit gives us:
+ *
+ *	uv = (2^2n + 2^n) (u1 v1)  +			[u1v1 = high]
+ *		 (2^n)    (u1 - u0) (v0 - v1)  +	[(u1-u0)... = mid]
+ *	       (2^n + 1)  (u0 v0)			[u0v0 = low]
+ *
+ * The terms (u1 v1), (u1 - u0) (v0 - v1), and (u0 v0) can all be done
+ * in just half the precision of the original.  (Note that either or both
+ * of (u1 - u0) or (v0 - v1) may be negative.)
+ *
+ * This algorithm is from Knuth vol. 2 (2nd ed), section 4.3.3, p. 278.
+ *
+ * Since C does not give us a `int * int = quad' operator, we split
+ * our input quads into two ints, then split the two ints into two
+ * shorts.  We can then calculate `short * short = int' in native
+ * arithmetic.
+ *
+ * Our product should, strictly speaking, be a `long quad', with 128
+ * bits, but we are going to discard the upper 64.  In other words,
+ * we are not interested in uv, but rather in (uv mod 2^2n).  This
+ * makes some of the terms above vanish, and we get:
+ *
+ *	(2^n)(high) + (2^n)(mid) + (2^n + 1)(low)
+ *
+ * or
+ *
+ *	(2^n)(high + mid + low) + low
+ *
+ * Furthermore, `high' and `mid' can be computed mod 2^n, as any factor
+ * of 2^n in either one will also vanish.  Only `low' need be computed
+ * mod 2^2n, and only because of the final term above.
