Perhaps register was the wrong word (I used it since that was the description in
the 'image_map' definition.

It's more of an index that points to individual colors in the image, with each
color having a distinct index. Starting at 0 or 1 (I forget which) then
increasing by 1 until each color has index.

The only problem is that shrinking it down to a single pixel, one of two things
could happen:

a) due to the reduced image, only 1 color remains and that color now has an
index of 1. the problem with this being you can't find the index of that color
with respect to the original picture

or

b) the image retains all the colors of the original image, even though only a
single color in a single pixel is being displayed. The palette thereby keeps the
same color index scheme, and you are back where you started (trying to find the
correct index for a color that has similar colors that are so close the human
eye can't distinguish between them.)
