Shading selects the material and render pass used to draw the box, using a value of the AdornShading enum. It defaults to Default, which draws the box unlit and occluded by scene geometry like an ordinary world object.

Shaded and XRayShaded light the box with the scene's lighting instead of drawing it unlit, while XRay and XRayShaded draw the box through geometry that would otherwise occlude it. AlwaysOnTop draws the box on top of everything else with no depth testing.

The legacy HandleAdornment.AlwaysOnTop property only takes effect while Shading is Default; any other Shading value determines the render pass on its own.
