presets are important for fast interaction with complex processing graphs. vkdt ships quite a few. to make them more accessible, comments inside the presets (see for instance https://github.com/hanatos/vkdt/blob/master/bin/data/presets/ColorChecker.pst) are parsed by the website generator and made into this site: https://jo.dreggn.org/vkdt/doc/howto/presets/presets.html

by for not all presets there have the best possible description. they should come with screenshots and cross-reference relevant modules in the docs.
