#3 Booklet repaginating

[Anonymous]

Blender could also treat pdf files so that they could
be printed like a brochure or a bunch of brochures. If
you have 8 pages 1 through 8, the new page order should
be:
8,1,2,7,6,3,4,5
where couples 8,1 and 6,3 should be printed on even
sides of the sheets, and couples 2,7 and 4,5 on odd
ones. So, the result will be a 8-page brochure, and
it'll occupy 2 sheets.

Of course, blender should add lacking pages (there must
be 4*n pages total) and perform page fitting to fit the
initial pages to half the new sheet's size minus
(maybe) user-defined margins.
