BT: QtDemo works far to sluggish on mac
Basically we need to revert more of Oliviers change. The reason is that we just cannot run the demo on mac without timer based updates (as opposed to graphics view itself tries to figure out when to update). The reason is that the demo uses QItemAnimations extensivelly, which again uses QTimelines, wich again uses separate timers. And on mac, because of coalesced updated, each item animation will result in an individual redrawing of the scene. Task-number: 255751 Reviewed-by: Olivier
