14%D This module has a more modern variant in xtables but as we follow a bit different
15%D approach with settings there, this mechanism will stay. In fact each of them has
16%D its advantages. This module could be sped up a bit and made more efficient by
17%D delegating some housekeeping to \LUA\ but it's not worth the effort. The code
18%D could me made more readable but again, there is no real purpose in it. If needed
19%D I can squeeze out a few more percentages runtime.
20
21% columndistance 'optimized' ... needs checking
22%
23% we don't need the alignment mechanism .. we can just pack the row in a box

65%D As always, this is the n\high{th} version. Much time went in trying to speed up
66%D the many cell calculations, some optimizations were rejected in order not to
67%D complicate this module too much (and in order to prevail extensibility). In the
68%D meantime we've sacrified some speed for readability.
