With this property, all panels can be displayed on and off
when the view is visible and invisible.

Code:

---

PANEL* myPanel = 
{
  pos_x = 0;
  pos_y = 0;
  //.....
  view = camera; 
}

---

This is the second time I request for this feature, I hope it
can be implemented in the future version of A7.

Thanks a lot!
