+/* Inside dimension is measure of nearby complexity, that reflects the energy
+   of nearby coefficients are nonzero.  For the first coefficient (DC, unless
+   block type is 0), we look at the (already encoded) blocks above and to the
+   left of the current block.  The context index is then the number (0,1,or 2)
+   of these blocks having nonzero coefficients.
+   After decoding a coefficient, the measure is determined by the size of the
+   most recently decoded coefficient.
+   Note that the intuitive meaning of this measure changes as coefficients
+   are decoded, e.g., prior to the first token, a zero means that my neighbors
+   are empty while, after the first token, because of the use of end-of-block,
+   a zero means we just decoded a zero and hence guarantees that a non-zero
+   coefficient will appear later in this block.  However, this shift
+   in meaning is perfectly OK because our context depends also on the
+   coefficient band (and since zigzag positions 0, 1, and 2 are in
+   distinct bands). */

+/* The warp filter for ROTZOOM and AFFINE models works as follows:
+   * Split the input into 8x8 blocks
+   * For each block, project the point (4, 4) within the block, to get the
+     overall block position. Split into integer and fractional coordinates,
+     maintaining full WARPEDMODEL precision
+   * Filter horizontally: Generate 15 rows of 8 pixels each. Each pixel gets a
+     variable horizontal offset. This means that, while the rows of the
+     intermediate buffer align with the rows of the *reference* image, the
+     columns align with the columns of the *destination* image.
+   * Filter vertically: Generate the output block (up to 8x8 pixels, but if the
+     destination is too small we crop the output at this stage). Each pixel has
+     a variable vertical offset, so that the resulting rows are aligned with
+     the rows of the destination image.
+
+   To accomplish these alignments, we factor the warp matrix as a
+   product of two shear / asymmetric zoom matrices:
+   / a b \  = /   1       0    \ * / 1+alpha  beta \
+   \ c d /    \ gamma  1+delta /   \    0      1   /
+   where a, b, c, d are wmmat[2], wmmat[3], wmmat[4], wmmat[5] respectively.
+   The second shear (with alpha and beta) is applied by the horizontal filter,
+   then the first shear (with gamma and delta) is applied by the vertical
+   filter.
+
+   The only limitation is that, to fit this in a fixed 8-tap filter size,
+   the fractional pixel offsets must be at most +-1. Since the horizontal filter
+   generates 15 rows of 8 columns, and the initial point we project is at (4, 4)
+   within the block, the parameters must satisfy
+   4 * |alpha| + 7 * |beta| <= 1   and   4 * |gamma| + 7 * |delta| <= 1
+   for this filter to be applicable.
+
+   Note: warp_affine() assumes that the caller has done all of the relevant
+   checks, ie. that we have a ROTZOOM or AFFINE model, that wm[4] and wm[5]
+   are set appropriately (if using a ROTZOOM model), and that alpha, beta,
+   gamma, delta are all in range.
