    workspacesView: Simplify syncing actual geometry
    
    We adjust the size and position of the primary view to match the workspaces
    display, but views on other monitors are always set to fill their monitor.
    
    Take that into account and create views with a fixed size and position, then
    only sync the primary view to the new geometry.
