[OpenLayers-Users] OL 2.13 generate unused html tags for PanControl

[Andreas Hocevar]

A Control.Panel is a control that wraps other controls. So for each control
that you add to a panel, you will get a div in the panel in addition to the
control's own div. Not saying that this makes sense, just saying that's the
way it is.
