Algorithm: Greedy orthogonal bipartition of RGB space for variance
minimization aided by inclusion-exclusion tricks.
For speed no nearest neighbor search is done. Slightly
better performance can be expected by more sophisticated
but more expensive versions.

The author thanks Tom Lane at Tom_Lane@G.GP.CS.CMU.EDU for much of
additional documentation and a cure to a previous bug.

Free to distribute, comments and suggestions are appreciated.

* Copyright (C) 1993-1997 Dennis Lee
*
* C implementation of DL3 Quantization.
* DL3 Quantization is a 2-pass color quantizer that uses an
* exhaustive search technique to minimize error introduced at
* each step during palData reduction.
*
* I believe DL3 Quantizer offers the highest quality of all existing
* color quantizers.  It is truly 'optimal' except for a few provisos.
* These provisos and other information about DL3 Quantizer can be found
* in DLQUANT.TXT, which is included in this distribution.
*
*
* NOTES
* =====
*
* The dithering code is based on code from the IJG's jpeg library.
*
* DL3 Quantization can take a long time to reduce a palData.
* Times can range from seconds to minutes or even hours depending on
* the image and the computer used.  This eliminates DL3 Quantizer for
* typical usage unless the user has a very fast computer and/or has a
* lot of patience.  However, the reward is a quantized image that is
* the best currently possible.  The number of colors in the source image,
* not the image size, determines the time required to quantize it.
*
* This source code may be freely copied, modified, and redistributed,
* provided this copyright notice is attached.
* Compiled versions of this code, modified or not, are free for
* personal use.  Compiled versions used in distributed software
* is also free, but a notification must be sent to the author.
* An e-mail to denlee@ecf.utoronto.ca will do.
