+Assuming that the bytes are stored `a00 a01 a02 a03 a10 .. a33`
+a 2D REMAP allows:
 
-* the column bytes (as a vec4) to be iterated over as an inner loop.

+* the column bytes (as a vec4) to be iterated over as an inner loop,
+  progressing vertically (`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.
