tdf#153162 Animation load optimizationHEADmaster

Loading a big GIF animation can freeze LO for a long time, so:

changed getAnimationFromGraphic, it can load parts of a big animation.
It can be called several times to load the whole animation.
Now it can load animation while it is playing.

It may still load smaller animations at once before it is rendered.
At first it load frames that sum maximum 5 million pixels.
(But minimum 10 frame.)

Changed the Graphic parameter to shared_ptr, so it won’t be deleted
until the whole animation is loaded.
