For each of EXT059 and EXT063:
DCT has dozens of uses in Audio-Visual processing and CODECs.
A full 8-wide in-place triple-loop Inverse DCT may be achieved

instructions. Expanding this to 16-wide is a matter of setting
`svshape 16` **and the same instructions used**.
Lee Composition may be deployed to construct non-power-two DCTs.
The cosine table may be computed (once) with 18 Vector instructions.
