Review comment (performance):
```suggestion

```
Use both `virtual` and `override`

Code after:

public:
	virtual String get_handle_name(int p_id, bool p_secondary) const override;
	virtual Variant get_handle_value(int p_id, bool p_secondary) const override;
	virtual void set_handle(int p_id, bool p_secondary, Camera3D *p_camera, const Point2 &p_point) override;
	virtual void commit_handle(int p_id, bool p_secondary, const Variant &p_restore, bool p_cancel = false) override;

	virtual void redraw() override;
	Path3DGizmo(Path3D *p_path = nullptr, float p_disk_size = 0.8);
};

class Path3DGizmoPlugin : public EditorNode3DGizmoPlugin {
	GDCLASS(Path3DGizmoPlugin, EditorNode3DGizmoPlugin);

	float disk_size = 0.8;

	// Locking basis is meant to ensure a predictable behavior during translation of the curve points in "local space transform mode".
	// Without the locking, the gizmo/point, in "local space transform mode", wouldn't follow a straight path and would curve and twitch in an unpredictable way.
