A 7zip archive with 4 PPT and ODB Lorem ipsum example presentations

I had to check and use in our training process some old presentations. These
had be made with LibreOffice 3.x.x and Microsoft Office Powerpoint. All of
these on that time worked just fine.

But now it is impossible to do the presentations as expected because
presentation stops on some places and can not follow up as expected.
The only way to get to the next slide is to stop presenting jump to the next
slide and start again by Shift+F5.
Unfortunately it happens several times and makes presenting of these
presentations with LibreOffice Impress a shame for the presenters.

After investigation I found that if some PNG or GIF pictures are set to use
zoom animation it breaks the presentation flow.
Same happens when some callout's are set to be zoomed by such animation.

The problem exist with PPT presentation and also with ODP presentations.

If some JPG pictures are set to be showed by a zoom animation it works
perfectly.

Unfortunately all LibreOffice 4.x.x may have same bug.
I can not check it as I do not have so old software, but asked the guis who
give me the presentations and they told me they had used them with LibreOffice
3.x.x Impress and Microsoft Office PowerPoint without any troubles.

Also I have checked and can confirm that same bug is available with the last
LibreOffice Version: 6.0.3.2 and LibreOffice Version: 5.4.6.2

Please see the attached here archive made by 7zip and you can see inside
examples of demo presentations to see the problem by uour own.
