Adds OriginDisplay plugin to draw the inertial axes in the scene.

Part of #332

Implements OriginDisplay plugin with ign-gui3. Note that there are no DisplayPlugins anymore so I had to retrieve the ScenePtr myself. I expect something similar for agent_info_display

the old visualizer has check boxes to toggle the axes. it's optional, but we could probably add one to the rectangle created by the plugin?

I was trying to figure out how to do this for the agent info display, but am a little slow at qml

I missed that.

I think I know how to do it. We should call a function from QML to C++. Something like:

• C++ callback
• QML execution

I imagine that you are trying to build some kind of checkbox. It inherits from Button so you can implement a function in the onClicked event:

Checkbox {
  id: checkboxId
  checked: Qt.Checked
  onClicked : {
    if (checkboxId.checked == Qt.Checked) {
      checkboxId.checked = Qt.Unchecked;
      AgentPlugin.YourSlotFunction(false);
    } else {
      checkboxId.checked = Qt.Checked;
      AgentPlugin.YourSlotFunction(true);
    }
  }
}

I'll implement the checkbox to toggle frame visibility

Toggle visibility was implemented in 5049e95

LGTM

nit: could be const.

btw why isVisible can't be used directly?

[agalbachicar]

I think it might change while changing the visibility of the axes.
