appreciated. by the time you wake up this is available as well, now:
it again uses triple generators to produce the (j, j+halfstep, k) indices - in
lock-step sequence - such that those can be used to "REMAP" standard
Vector array indices 0 1 2 3.
and, now that i look at it, i realised that there are not actually 3
there is actually only one (the 2^N FFT array size). this means that the ydim
and zdim parameters in the SVSHAPE SPR are *not needed* and thus can
be used for extra "mode" bits.
