    Make inset info icons tight again!
    
    This is a follow-up to 5be391b2, which increased the space on
    left/right of graphics inset. This extra space makes sense in normal
    graphics editing, but is weird in the case of InsetInfo, which has its
    own spacing.
    
    Create a special tight graphics inset class, and use that for icons.
