- * This is a speed-up version of the inverse 2D slant transforms
- * for the case if there is a non-zero DC coeff and all AC coeffs are zero.
+ * DC-only two-dimensional inverse slant transform.
* Performing the inverse slant transform in this case is equivalent to
* spreading (DC_coeff + 1)/2 over the whole block.
* It works much faster than performing the slant transform on a vector of zeroes.
