halftoning pattern.

* Allow bayer:256 constructs, which do the same as bayer:256x256.

* stock.c: add new error diffusion kernels: Fan, Shiau-Fan, Stucki, Burkes,
Sierra, two-row Sierra, Filter Lite.

* Get rid of the specific error diffusion functions, since our stock kernels
work perfectly well.

* Do not prefix stock image names with "pipi:", it's redundant.

* stock.c: the random stock image now creates RGB noise.

* stock.c: allow arbitrary sizes for the bayer stock image, even if they
give shitty results when used for ordered dithering.

* codec.c: support for stock images in pipi_load().
* stock.c: start working on stock image generation; for instance:
pipi pipi:bayer64 -o image.png
will generate a 64x64 Bayer dithering pattern and save it to image.png.
