 REMAP allows the usual vector loop `0..VL-1` to be "reshaped" (re-mapped)
 from a linear form to a 2D or 3D transposed form, or "offset" to permit

 The initial primary motivation of REMAP was for Matrix Multiplication, reordering of sequential
 data in-place.  Four SPRs are provided so that a single FMAC may be

 such as RGB pixel data extraction and reforming.
