<!--
    The reason we need the "placer" is so we can scale the bank frame and
    still have the UIPanel placement stuff automatically place it in the
    same location that the bank usually appears. ShowUIPanel doesn't take
    into account the child scale and calls SetPoint on it in UIParent coords
    which if the child is a different scale will put it in the wrong place.

    Then we have to go to some annoying effort to keep the placer sized
    the same as the actual bank frame.

    UIPanelLayout stuff so the Blizzard UIParent code will position us
    automatically. See
      http://www.wowwiki.com/Creating_standard_left-sliding_frames
    but note that UIPanelLayout-enabled isn't a thing at all.
