This is a MonoBehaviour serves as the base of all the panels for Immersive Debugger.

Basically it utilizes the OVROverlay (within the customized OverlayCanvas) so the rendering is done in overlay layer (composition layer) instead of projection layer. Note the panel will only use the overlay layer in the runtime (not in Editor / Link). It could help the panels display much sharper text. See more in the OVROverlay doc.
