--- Comment #16 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
also Matrix REMAP is very expensive to set up, large latency expected,
four SVSHAPE SPRs to be written to, where PACK/UNPACK is 2 bits in
SVSHAPE and consequently extremely quick to establish. this has *all*
been written in detail in the spec, *please* read it.
