remapping occurs first and the Index lookup second. Thus it
becomes possible to perform in-place Transpose of Indices which
may have been costly to set up or costly to duplicate
-(waste register file space).
+(waste register file space). In other words: it is fine for two or more
+SVSHAPEs to simultaneously use the same
+Indices, but one SVSHAPE has different 2D dimensions and ordering from the others.
