Sample ODP

Make sure the setting 'Use OpenGL for all rendering' is set in Tools ->
Options...; LibreOffice -> View.
Open the attached presentation, which has a shape with an entrance animation
(Venetian Blinds) set to start 'With previous' (it's the same with 'After
previous').
Play slideshow.

=> Shape appears immediately, without animation.


Further observations:
- There is animation if start is set to 'On click'.
- There is animation if 'Use OpenGL for all rendering' is turned off.
- The issue is generic, other animations seem to be affected as well.

Reproduced using LO 5.4.1.2, 5.2.0.4 and 5.1.6.2 / Windows 7.
Not reproduced using LO 5.1.0.3 (there is a crash when the slideshow is
finished, though).
=> regression

Since this depends on the VCL OpenGL setting, I'm adding it to that tracker.

Bibisected to the following commit using bibisect-win32-5.1, though it seems
like the change just exposed the issue, and not caused it. Adding Cc: to
Michael Meeks nevertheless.
