Well, the *original* way people used to do this for 2-D arrays (in
assembly and HLLs like C) was to create a table of pointers that point
at the beginning of each row in the array. Fetch the pointer with the
leftmost index (assuming row-major ordering) and then add the second
index to this base address.
That is what I ended up discovering to be the fastest solution for my
particular situation.
