Here is my MWE. Think of a photo album. To make it interesting the pages should
all be different. To this purpose layers are a good means. I'd like to centre
the layers on their page without doing so manually and without changig the distances
between them. Using luacode one can calculate the distance d between the leftmost
and the rightmost edge. Half the difference (\textwidth - d) is the amount to move
the whole layer ensemble.
My question is now: Does in context exist a possibility to move all layers jointly
without correcting all their x-values subsequently?
I append the pdf-file of my MWE.
