-- == Description
--
-- Rasterization has been the dominant method to produce interactive
-- graphics, but increasing performance of graphics hardware has made ray
-- tracing a viable option for interactive rendering. Being able to
-- integrate ray tracing with traditional rasterization makes it easier for
-- applications to incrementally add ray traced effects to existing
-- applications or to do hybrid approaches with rasterization for primary
-- visibility and ray tracing for secondary queries.
--
-- Ray queries are available to all shader types, including graphics,
-- compute and ray tracing pipelines. Ray queries are not able to launch
-- additional shaders, instead returning traversal results to the calling
-- shader.
--
-- This extension adds support for the following SPIR-V extension in
-- Vulkan:
--
-- -   @SPV_KHR_ray_query@
--
-- == New Structures
--
-- -   Extending
--     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceFeatures2',
--     'Vulkan.Core10.Device.DeviceCreateInfo':
--
--     -   'PhysicalDeviceRayQueryFeaturesKHR'
--
-- == New Enum Constants
--
-- -   'KHR_RAY_QUERY_EXTENSION_NAME'
--
-- -   'KHR_RAY_QUERY_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_PHYSICAL_DEVICE_RAY_QUERY_FEATURES_KHR'
--
-- == New SPIR-V Capabilities

--
-- Example of ray query in a GLSL shader
--
-- > rayQueryEXT rq;
-- >
-- > rayQueryInitializeEXT(rq, accStruct, gl_RayFlagsNoneEXT, 0, origin, tMin, direction, tMax);
-- >
-- > while(rayQueryProceedEXT(rq)) {
-- >     if (rayQueryGetIntersectionTypeEXT(rq, false) == gl_RayQueryCandidateIntersectionTriangleEXT) {
-- >         //...
-- >         rayQueryConfirmIntersectionEXT(rq);
-- >     }
-- > }
-- >
-- > if (rayQueryGetIntersectionTypeEXT(rq, true) == gl_RayQueryCommittedIntersectionNoneEXT) {
-- >     //...
-- > }
--
-- == Issues
--
-- (1) What are the changes between the public provisional
-- (VK_KHR_ray_tracing v8) release and the final
-- (VK_KHR_acceleration_structure v11 \/ VK_KHR_ray_query v1) release?
--
-- -   refactor VK_KHR_ray_tracing into 3 extensions, enabling
--     implementation flexibility and decoupling ray query support from ray
--     pipelines:
--
--     -   @VK_KHR_acceleration_structure@ (for acceleration structure
--         operations)
--
--     -   @VK_KHR_ray_tracing_pipeline@ (for ray tracing pipeline and
--         shader stages)
--
--     -   @VK_KHR_ray_query@ (for ray queries in existing shader stages)
--
-- -   Update SPIRV capabilities to use @RayQueryKHR@
--
-- -   extension is no longer provisional
--
-- == Version History
--
-- -   Revision 1, 2020-11-12 (Mathieu Robart, Daniel Koch, Andrew Garrard)
--
--     -   Decomposition of the specification, from VK_KHR_ray_tracing to
--         VK_KHR_ray_query (#1918,!3912)
--
--     -   update to use @RayQueryKHR@ SPIR-V capability
--
--     -   add numerical limits for ray parameters (#2235,!3960)
--
--     -   relax formula for ray intersection candidate determination
--         (#2322,!4080)
--
--     -   restrict traces to TLAS (#2239,!4141)
--
--     -   require @HitT@ to be in ray interval for
--         @OpRayQueryGenerateIntersectionKHR@ (#2359,!4146)
--
--     -   add ray query shader stages for AS read bit (#2407,!4203)
