This is not exactly the same but quite similar to the 'unroll' primitive
for TeXmacs slides (not documented, unfortunately). You should take a look
at fold-edit.scm, fold-menu.scm, etc. and see whether you can hack
a new effect 'progressive'. You probably will have to implement both
a block and an inline variant.
