--
-- == Description
--
-- The @VK_KHR_variable_pointers@ extension allows implementations to
-- indicate their level of support for the @SPV_KHR_variable_pointers@
-- SPIR-V extension. The SPIR-V extension allows shader modules to use
-- invocation-private pointers into uniform and\/or storage buffers, where
-- the pointer values can be dynamic and non-uniform.
--
-- The @SPV_KHR_variable_pointers@ extension introduces two capabilities.
-- The first, @VariablePointersStorageBuffer@, /must/ be supported by all
-- implementations of this extension. The second, @VariablePointers@, is
-- optional.
--
-- == Promotion to Vulkan 1.1
--
-- All functionality in this extension is included in core Vulkan 1.1, with
-- the KHR suffix omitted, however support for the
-- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#features-variablePointersStorageBuffer variablePointersStorageBuffer>
-- feature is made optional. The original type, enum and command names are
-- still available as aliases of the core functionality.
--
-- == New Structures
--
-- -   Extending
--     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceFeatures2',
--     'Vulkan.Core10.Device.DeviceCreateInfo':
--
--     -   'PhysicalDeviceVariablePointerFeaturesKHR'
--
--     -   'PhysicalDeviceVariablePointersFeaturesKHR'
--
-- == New Enum Constants
--
-- -   'KHR_VARIABLE_POINTERS_EXTENSION_NAME'
--
-- -   'KHR_VARIABLE_POINTERS_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'STRUCTURE_TYPE_PHYSICAL_DEVICE_VARIABLE_POINTERS_FEATURES_KHR'
--
--     -   'STRUCTURE_TYPE_PHYSICAL_DEVICE_VARIABLE_POINTER_FEATURES_KHR'
--
-- == New SPIR-V Capabilities
--
-- -   <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#spirvenv-capabilities-table-VariablePointers VariablePointers>

-- -   <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#spirvenv-capabilities-table-VariablePointersStorageBuffer VariablePointersStorageBuffer>
--
-- == Issues
--
-- 1) Do we need an optional property for the SPIR-V
-- @VariablePointersStorageBuffer@ capability or should it be mandatory
-- when this extension is advertised?
--
-- __RESOLVED__: Add it as a distinct feature, but make support mandatory.
-- Adding it as a feature makes the extension easier to include in a future
-- core API version. In the extension, the feature is mandatory, so that
-- presence of the extension guarantees some functionality. When included
-- in a core API version, the feature would be optional.
--
-- 2) Can support for these capabilities vary between shader stages?
--
-- __RESOLVED__: No, if the capability is supported in any stage it must be
-- supported in all stages.
--
-- 3) Should the capabilities be features or limits?
--
-- __RESOLVED__: Features, primarily for consistency with other similar
-- extensions.
