-// Note: Fixed size intermediate buffers, place limits on parameters
-// of some functions. 2d filtering proceeds in 2 steps:
-// (1) Interpolate horizontally into an intermediate buffer, temp.
-// (2) Interpolate temp vertically to derive the sub-pixel result.
-// Deriving the maximum number of rows in the temp buffer (135):
-// --Smallest scaling factor is x1/2 ==> y_step_q4 = 32 (Normative).
-// --Largest block size is 64x64 pixels.
-// --64 rows in the downscaled frame span a distance of (64 - 1) * 32 in the
-// original frame (in 1/16th pixel units).
-// --Must round-up because block may be located at sub-pixel position.
-// --Require an additional SUBPEL_TAPS rows for the 8-tap filter tails.
-// --((64 - 1) * 32 + 15) >> 4 + 8 = 135.
-// TODO(wtc): Update the above comment to explain the value 263 used in aom.
