 Function `Axis(ImVec2 pos, const glm::mat4& modelView, float size = 20.f)`
 which display right-handed axis in a ImGui window.

 Example

 ```cpp
       {  // Display orientation axis at the bottom left corner of the window
        float  axisSize = 25.F;
        ImVec2 pos      = ImGui::GetWindowPos();
        pos.y += ImGui::GetWindowSize().y;
        pos += ImVec2(axisSize * 1.1F, -axisSize * 1.1F) * ImGui::GetWindowDpiScale();  // Offset
        ImGuiH::Axis(pos, CameraManip.getMatrix(), axisSize);
      }
```
