+ * most);
+ * - [-w-1..-2*w] will be the bottom/left edge pixels.
+ * Each edge may remain uninitialized if it is not used by the returned mode
+ * index. If edges are not available (because the edge position is outside the

+/*A range decoder.
+ This is an entropy decoder based upon \cite{Mar79}, which is itself a+ rediscovery of the FIFO arithmetic code introduced by \cite{Pas76}.+ It is very similar to arithmetic encoding, except that encoding is done with
+ digits in any base, instead of with bits, and so it is faster when using
+ larger bases (i.e.: a byte).
+ The author claims an average waste of $\frac{1}{2}\log_b(2b)$ bits, where $b$+ is the base, longer than the theoretical optimum, but to my knowledge there
+ is no published justification for this claim.
+ This only seems true when using near-infinite precision arithmetic so that
+ the process is carried out with no rounding errors.
+
+ An excellent description of implementation details is available at
+ http://www.arturocampos.com/ac_range.html
+ A recent work \cite{MNW98} which proposes several changes to arithmetic+ encoding for efficiency actually re-discovers many of the principles
+ behind range encoding, and presents a good theoretical analysis of them.
+
+ End of stream is handled by writing out the smallest number of bits that
+ ensures that the stream will be correctly decoded regardless of the value of
+ any subsequent bits.
+ od_ec_dec_tell() can be used to determine how many bits were needed to decode
+ all the symbols thus far; other data can be packed in the remaining bits of
+ the input buffer.

+ * Changes made compared to libaom version:

+ * 8x8 resolution, and therefore shared between cur_frame
+ * and prev_frame. To make enc/dec behave consistent, we
+ * also make this change around line 2580:
+#if 0
+ AOMMIN(((mi_row >> 1) << 1) + 1 + (((xd->n8_h - 1) >> 1) << 1),
+ mi_row_end - 1) *
+ prev_frame_mvs_stride +

+#else
+ (((mi_row >> 1) << 1) + 1) * prev_frame_mvs_stride +
+ (((mi_col >> 1) << 1) + 1)
+#endif
+ * and the same change (swap mi_cols from prev_frame.mv_stride) on line 2407
+ * - we disable rect-block overhanging edge inclusion (see
+ * line 2642):
