But I'm open to any ideas you may have as to how we could avoid using
floats, yet not run into the overflow situations so easily. We could
probably use division somewhere but I don't think that's actually any
better performance-wise.
It is, when implemented via bit-shifts (very cheap). I know w

Only because in this instance it is used with integer data. It doesn't
need to be limited to just integer values. B

As I explained previously, this algorithm makes no assumptions about the
data that is being queried. Just because in this case (patch 3) we are
working with RGB colour data doesn't mean it is limited to only that. It
will work with *any* values, as

Make use of the Triangle Inequality Nearest Neighbour algorithm to find the
nearest colour more efficiently than a simple linear search. The improvements
are most noticeable with a palette of 256 colours. Testing shows approximately
