Experiments with adding preload instructions to this function yielded no
useful benefit, so these have not been included.

The assembly version has also been tested with a fuzz tester to ensure that
any combinations of inputs not exercised by my available test streams still
generate mathematically identical results to the C version.

There is no point in having a separate file just for the instantiation
that provides the public functions.

There is no point in having this separate; it is not used as a template.

The functions are not used templatized.

The indirection makes no sense without multiple instantiation.

The indirection makes no sense without multiple instantiation.

This allows detemplatizing the bits that are not instantiated twice.

Multiple inclusion makes no sense as it is only used in the 8-bit case.

This fixes FATE with mmxext CPUFLAGS set.

Fixes ticket #3495.

Both of these dithering methods are from http://pippin.gimp.org/a_dither/ for
GIF they can be considered better than bayer (provides more gray-levels), and
spatial stability - often more than twice as good compression and less visual
flicker than error diffusion methods (the methods also avoids error-shadow
artifacts of diffusion dithers).

These methods are similar to blue/green noise type dither masks; but are
simple enough to generate their mask on the fly. They are still research work
in progress; though more expensive to generate masks (which can be used in a
LUT) like 'void and cluster' and similar methods will yield superior results
