    sizegroup: Skip resizes on widgets that have resize queued
    
    Widgets that already have a resize queued don't need to walk the whole
    parent chain and queue another resize. It's enough to do it once per
    resize.
    
    This also means that sizegroups cannot use the shortcut of just
    invalidating the first widget in the group anymore. That widget might
    already have a resize queued while others don't.
