commit 4087b7c9d1a190e32129e8e319ecba93da7dd75a
Author: Jehan <jehan girinstud io>

plug-ins: support animation cycles with several layers in a cell.
If the layers all have the same numbering scheme, then successive
frames in the suite will follow this common scheme (which could result
in some frames having less layers than the next ones in the cycle).
Otherwise this is like merging 2 sequential suite without any link
in their respective numbering.
