The said patch

For very complex map files (that sometimes take minutes to render) it is a good
idea (and Adobe Reader does the same) to update the rendered image every X
operations so that the user sees the rendering is still happening instead of
the program to have hung.

This is already taken into account in the poppler core by the calls to dump()
from Gfx.cc.

This patch leverages that and adds new API to the Qt5 frontend to allow for
that.

I will add a link to the Okular code that uses it in a bit.

I will also try to find a slow document to share, since the one i've used to
develop this feature is sadly private and can't share it.
