    layout: Don't use the actors pick workaround on update regions
    
    As per introduction of geometric picking in mutter [1], the workaround we
    had consisting in picking all the actors to ensure that all the stage
    projections were computed to get valid actors stage-transformed coordinates
    and sizes is not working anymore as there is more caching involved.
    
    However since this can be now handled properly in mutter [2], initializing a
    valid projection matrix since the beginning, we can get rid of the
    workaround.
