Emitted after the ::begin-print signal, but before the actual rendering
starts.
It keeps getting emitted until a connected signal handler returns %TRUE.
The ::paginate signal is intended to be used for paginating a document
in small chunks, to avoid blocking the user interface for a long
time. The signal handler should update the number of pages using
[method@Gtk.PrintOperation.set_n_pages], and return %TRUE if the document
has been completely paginated.
If you don't need to do pagination in chunks, you can simply do
it all in the ::begin-print handler, and set the number of pages
from there.
