+    It contains the value of zzi BEFORE the final token in the block was
+     decoded.
+    In most cases this is an EOB token (the continuation of an EOB run from a
+     previous block counts), and so this is the same as the coefficient count.
+    However, in the case that the last token was NOT an EOB token, but filled
+     the block up with exactly 64 coefficients, _last_zzi will be less than 64.
+    Provided the last token was not a pure zero run, the minimum value it can
+     be is 46, and so that doesn't affect any of the cases in this routine.
+    However, if the last token WAS a pure zero run of length 63, then _last_zzi
+     will be 1 while the number of coefficients decoded is 64.
+    Thus, we will trigger the following special case, where the real
+     coefficient count would not.
+    Note also that a zero run of length 64 will give _last_zzi a value of 0,
+     but we still process the DC coefficient, which might have a non-zero value
+     due to DC prediction.
+    Although convoluted, this is arguably the correct behavior: it allows us to
+     use a smaller transform when the block ends with a long zero run instead
+     of a normal EOB token.
+    It could be smarter... multiple separate zero runs at the end of a block
+     will fool it, but an encoder that generates these really deserves what it
+     gets.
+    Needless to say we inherited this approach from VP3.*/
