--
-- == Description
--
-- This extension provides a new mechanism allowing applications to
-- generate collections of geometric primitives via programmable mesh
-- shading. It is an alternative to the existing programmable primitive
-- shading pipeline, which relied on generating input primitives by a fixed
-- function assembler as well as fixed function vertex fetch.
--
-- There are new programmable shader types — the task and mesh shader — to
-- generate these collections to be processed by fixed-function primitive
-- assembly and rasterization logic. When task and mesh shaders are
-- dispatched, they replace the core
-- <https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#pipeline-graphics-subsets-pre-rasterization pre-rasterization stages>,
-- including vertex array attribute fetching, vertex shader processing,
-- tessellation, and geometry shader processing.
--
-- This extension also adds support for the following SPIR-V extension in
-- Vulkan:

--
-- == Issues
--
-- 1.  How to name this extension?
--
--     __RESOLVED__: VK_NV_mesh_shader
--
--     Other options considered:
--
--     -   VK_NV_mesh_shading
--
--     -   VK_NV_programmable_mesh_shading
--
--     -   VK_NV_primitive_group_shading
--
--     -   VK_NV_grouped_drawing
--
-- 2.  Do we need a new VkPrimitiveTopology?
--
--     __RESOLVED__: No. We skip the InputAssembler stage.
--
-- 3.  Should we allow Instancing?
--
--     __RESOLVED__: No. There is no fixed function input, other than the
--     IDs. However, allow offsetting with a “first” value.
--
-- 4.  Should we use existing vkCmdDraw or introduce new functions?
--
--     __RESOLVED__: Introduce new functions.
--
--     New functions make it easier to separate from “programmable
--     primitive shading” chapter, less “dual use” language about existing
--     functions having alternative behavior. The text around the existing
--     “draws” is heavily based around emitting vertices.
--
-- 5.  If new functions, how to name?
--
--     __RESOLVED__: CmdDrawMeshTasks*
--
--     Other options considered:
--
--     -   CmdDrawMeshed
--
--     -   CmdDrawTasked
--
--     -   CmdDrawGrouped
--
-- 6.  Should VK_SHADER_STAGE_ALL_GRAPHICS be updated to include the new
--     stages?
--
--     __RESOLVED__: No. If an application were to be recompiled with
--     headers that include additional shader stage bits in
--     VK_SHADER_STAGE_ALL_GRAPHICS, then the previously valid application
--     would no longer be valid on implementations that do not support mesh
--     or task shaders. This means the change would not be backwards
--     compatible. It is too bad VkShaderStageFlagBits does not have a
--     dedicated “all supported graphics stages” bit like
--     VK_PIPELINE_STAGE_ALL_GRAPHICS_BIT, which would have avoided this
--     problem.
