* from an algorithm thread for instance,
* that the animation passed as parameter leaves in the gui-thread,
* so that it can perform flawlessly.
*
* Indeed, IN THAT CASE, performing a direct call to QAbstractAnimation::start causes the animation
* not to perform in the way it should. So we first move it to the gui-thread and then
* emit a signal which finally triggers its execution.
*
* This isn't probably the best way to address this issue, but it works.
