--- Comment #2 from Aron Budea <baron at caesar.elte.hu> ---
One of the issues is that the <p:val> element of type p:fltVal is not exported.

original snippet:
  <p:tavLst>
    <p:tav tm="0">
      <p:val>
        <p:fltVal val="0"/>
      </p:val>
    </p:tav>
    <p:tav tm="100000">
      <p:val>
        <p:strVal val="#ppt_w"/>
      </p:val>
    </p:tav>
  </p:tavLst>

exported snippet:
  <p:tavLst>
    <p:tav tm="0">
      <p:val/>
    </p:tav>
    <p:tav tm="100000">
      <p:val>
        <p:strVal val="#ppt_w"/>
      </p:val>
    </p:tav>
  </p:tavLst>

The code doesn't like p:fltVal for Width attribute, see what's in the 'if'
around here:
https://opengrok.libreoffice.org/xref/core/sd/source/filter/eppt/pptexanimations.cxx#1390

Not sure what's allowed, since conversion seems to be involved in general, but
maybe interpreting a double with the value 0 could be allowed there?
Adding that still exports a p:strVal instead of p:fltVal, though, so further
changes are needed.
