+/* This is a modified version of 'warped_filter' from warped_motion.c:
+   * Each coefficient is stored in 8 bits instead of 16 bits
+   * The coefficients are rearranged in the column order 0, 2, 4, 6, 1, 3, 5, 7
+
+     This is done in order to avoid overflow: Since the tap with the largest
+     coefficient could be any of taps 2, 3, 4 or 5, we can't use the summation
+     order ((0 + 1) + (4 + 5)) + ((2 + 3) + (6 + 7)) used in the regular
+     convolve functions.
+
+     Instead, we use the summation order
+     ((0 + 2) + (4 + 6)) + ((1 + 3) + (5 + 7)).
+     The rearrangement of coefficients in this table is so that we can get the
+     coefficients into the correct order more quickly.

+// 8 (3 bits) over the scale of the pixel values.  Thus, for 8-bit
+// input, the coefficients have effectively 11 bits of scale depth
+// (8+3), 10-bit input pixels result in 13-bit coefficient depth
+// (10+3) and 12-bit pixels yield 15-bit (12+3) coefficient depth.
+// All quantizers are built using this invariant of x8, 3-bit scaling,

+// A partial exception to this rule is large transforms; to avoid
+// overflow, TX blocks with > 256 pels (>16x16) are scaled only
+// 4-times unity (2 bits) over the pixel depth, and TX blocks with
+// over 1024 pixels (>32x32) are scaled up only 2x unity (1 bit).
+// This descaling is found via av1_tx_get_scale().  Thus, 16x32, 32x16

+// 64x32 and 64x64 transforms return Q1 coefficients.  However, the

+// (av1_tx_get_scale()) during quantization, and as such the
+// dequantized/decoded coefficients, even for large TX blocks, are always
+// effectively Q3. Meanwhile, quantized/coded coefficients are Q0
+// because Qn quantizers are applied to Qn tx coefficients.
+
+// Note that encoder decision making (which uses the quantizer to
+// generate several bespoke lamdas for RDO and other heuristics)
+// expects quantizers to be larger for higher-bitdepth input.  In

+//   In this case, we use the 3 rows of CDEF output across the boundary for
+//   context; this corresponds to leaving the frame buffer as-is.
+//
+// * If we're at a tile boundary and loop filtering across tiles is disabled,
+//   then we take the outermost row of CDEF pixels *within the current tile*
+//   and copy it three times. Thus we behave exactly as if the tile were a full
+//   frame.
+//
+// * Otherwise, we're at a stripe boundary within a tile. In that case, we
+//   take 2 rows of deblocked pixels and extend them to 3 rows of context.

+/* 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 horizontal shear (with alpha and beta) is applied first,
+   then the vertical shear (with gamma and delta) is applied second.
+
+   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| + 4 * |delta| <= 1
+   for this filter to be applicable.
+
+   Note: This function 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.

+/* A note on hardware implementation:
+    The warp filter is intended to be implementable using the same hardware as
+    the high-precision convolve filters from the loop-restoration and
+    convolve-round experiments.
+
+    For a single filter stage, considering all of the coefficient sets for the
+    warp filter and the regular convolution filter, an input in the range
+    [0, 2^k - 1] is mapped into the range [-56 * (2^k - 1), 184 * (2^k - 1)]
+    before rounding.
+
+    Allowing for some changes to the filter coefficient sets, call the range
+    [-64 * 2^k, 192 * 2^k]. Then, if we initialize the accumulator to 64 * 2^k,
+    we can replace this by the range [0, 256 * 2^k], which can be stored in an
+    unsigned value with 8 + k bits.
+
+    This allows the derivation of the appropriate bit widths and offsets for
+    the various intermediate values: If
+
+    F := FILTER_BITS = 7 (or else the above ranges need adjusting)
+         So a *single* filter stage maps a k-bit input to a (k + F + 1)-bit
+         intermediate value.
+    H := ROUND0_BITS
+    V := VERSHEAR_REDUCE_PREC_BITS
+    (and note that we must have H + V = 2*F for the output to have the same
+     scale as the input)
+
+    then we end up with the following offsets and ranges:
+    Horizontal filter: Apply an offset of 1 << (bd + F - 1), sum fits into a
+                       uint{bd + F + 1}
+    After rounding: The values stored in 'tmp' fit into a uint{bd + F + 1 - H}.
+    Vertical filter: Apply an offset of 1 << (bd + 2*F - H), sum fits into a
+                     uint{bd + 2*F + 2 - H}
+    After rounding: The final value, before undoing the offset, fits into a
+                    uint{bd + 2}.
+
+    Then we need to undo the offsets before clamping to a pixel. Note that,
+    if we do this at the end, the amount to subtract is actually independent
+    of H and V:
+
+    offset to subtract = (1 << ((bd + F - 1) - H + F - V)) +
+                         (1 << ((bd + 2*F - H) - V))
+                      == (1 << (bd - 1)) + (1 << bd)
+
+    This allows us to entirely avoid clamping in both the warp filter and
+    the convolve-round experiment. As of the time of writing, the Wiener filter
+    from loop-restoration can encode a central coefficient up to 216, which
+    leads to a maximum value of about 282 * 2^k after applying the offset.
+    So in that case we still need to clamp.

+   * Each coefficient is stored in 8 bits instead of 16 bits
+   * The coefficients are rearranged in the column order 0, 2, 4, 6, 1, 3, 5, 7
+
+     This is done in order to avoid overflow: Since the tap with the largest
+     coefficient could be any of taps 2, 3, 4 or 5, we can't use the summation
+     order ((0 + 1) + (4 + 5)) + ((2 + 3) + (6 + 7)) used in the regular
+     convolve functions.
+
+     Instead, we use the summation order
+     ((0 + 2) + (4 + 6)) + ((1 + 3) + (5 + 7)).
+     The rearrangement of coefficients in this table is so that we can get the
