CloseOverlayCanvas is a container for collections of Overlays.
Every EditorWindow has an OverlayCanvas, but only windows that opt-in to Overlay support will display Overlays. See ISupportsOverlays for more information.
| Add | Add an Overlay to this canvas. Added Overlays will be displayed in the associated EditorWindow until they are removed. |
| OnAfterDeserialize | Invoked after OverlayCanvas is deserialized. |
| OnBeforeSerialize | Invoked before OverlayCanvas will be serialized. This is used to store Overlay layout data. |
| Remove | Remove an Overlay from this canvas. Removed Overlays are disassociated from OverlayCanvas and the related EditorWindow, but not destroyed. This means you are able to move a single Overlay between multiple windows. |
