winex11: Add implementation of Triangle Inequality Nearest Neighbour algorithm. (try 2)

[Vitaly Budovski]

This will allow faster palette lookups for 8 bit palettes.

This may come up in a reply, so I'll address it now. Float must be used
since an int doesn't provide enough range for the numbers we are dealing
with.

Fixed the unintentional change to a comment.
