It seems 2.1 decided to make life difficult in that is has removed the helper assembler2pipepictures(), further there are new(? to me at least!) files __base__/graphics/entity/assembling-machine-2/assembling-machine-2-pipe-N.lua for example that now contain the width/height/shift/line_length.
... I sidestepped the issue by blatant copy/paste for now, but it'd probably be a better longer term solution if instead imported/loaded from those files. DIFFPATCH of what I did to get it working-hacky-ish below for reference.
