Presentation with "mouse as pen" shapes

While bibisecting bug 129898, I found that my test presentation would
automatically be set as modified, after closing the presentation mode, without
having done any changes.

To reproduce:

1. Open the attached presentation (and you'll notice bug 129898 too)
2. Start the presentation (F5)
3. Finish the presentation using the keyboard (space), so you won't
accidentally draw something.

Actual result: the presentation is modified and you will get asked to save the
changes when closing it

Expected result: no modification to the presentation, no dialog on close

This was introduced by:

    commit 516ecd072f9dbfbacce77127a02b666ce387982d

        Restore persistent userpaint functionality in slideshow.

You'll also notice, that finishing the presentation mode has now quite a lag
after this commit. Copying the drawing from the presentation window seems very
slow, which showing the presentation with the drawing on it, still feels
instant.
