[gnome-shell/wip/exalm/gestures: 9/10] workspaceAnimation: Use window clones



commit 0cc7787897a7bf961fdd97d9c6f11b8c5f9de839
Author: Alexander Mikhaylenko <alexm gnome org>

    workspaceAnimation: Use window clones
    
    Instead of reparenting windows, clone them. This will allow to properly
    support multi-monitor setups in subsequent commits.
    
    Block window mapping animation while the animation is running to prevent
    new windows appearing during the animation from being visible at the same
    time as their clones.
