-// NOTE(david.barker): The input and output of aom_blend_a64_d32_mask_c() are
-// in a higher intermediate precision, and will later be rounded down to pixel
-// precision.
-// Thus, in order to avoid double-rounding, we want to use normal right shifts
-// within this function, not ROUND_POWER_OF_TWO.
-// This works because of the identity:
-// ROUND_POWER_OF_TWO(x >> y, z) == ROUND_POWER_OF_TWO(x, y+z)
-//
-// In contrast, the output of the non-d32 functions will not be further rounded,
-// so we *should* use ROUND_POWER_OF_TWO there.
