    //! This test checks the functionality of ray tracing intersection shaders for procedural geometry by generating the following scene:
    //!  - A horizontal plane with mirror material
    //!  - A number of sphere and box shapes (from the DebugDraw gem) with enabled ray tracing setting
    //!  - A SpecularReflections level component with "Ray tracing" reflection method
    //! The DebugDraw gem supplies the intersection shaders for the sphere and box shapes and adds them to the ray tracing scene. The shapes
    //! are therefore visible as ray-traced reflections in the mirror plane.
