aha, forgot to multiply the texture features by 0.2357. (why is this a magic number?). texture features now seem to be below 1, but not below 0.4
found a bug in 'norm' calculation ... forgot to offset by 'i'.
aha, forgot to square the norm. i see a lot less '0.4' in the output csv now.
visually, my results match voc5 results. it's just the edge conditions and place features that are throwing the match accuracy off, I think. and possibly a shift left or right by a pixel or two.

~95ms on my laptop with openmp, for the same task.
