LD all sorted, scaled it back to LD-with-shift, and if pushed we could
do without LDsh entirely.

the DCT/iDCT REMAP schedule now does bitrev-with-halfswap itself,
applying that to the offset.

i cannot say i am happy about losing LD-bitrev because FFT was very
short, with it.

iDCT unit test with LD, inner and outer butterfly works great.

next is to write a program that creates SVG files to put into docs and slides.
