An example where SUBVL Remap is appropriate is the Rijndael MixColumns stage:
A 2D REMAP allows:
* the column bytes (as a vec4) to be iterated over as an inner loop.
+ (`a00 a10 a20 a30`)
* the columns themselves to be iterated as an outer loop
* a 32 bit `GF(256)` multiply on the vec4 to be performed.
