--
-- == Description
--
-- This extension allows list primitives to use the primitive restart index
-- value. This provides a more efficient implementation when layering
-- OpenGL functionality on Vulkan by avoiding emulation which incurs data
-- copies.
--
-- == New Structures
--
-- -   Extending
--     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceFeatures2',
--     'Vulkan.Core10.Device.DeviceCreateInfo':
--
--     -   'PhysicalDevicePrimitiveTopologyListRestartFeaturesEXT'
--
-- == New Enum Constants
--
-- -   'EXT_PRIMITIVE_TOPOLOGY_LIST_RESTART_EXTENSION_NAME'
--
-- -   'EXT_PRIMITIVE_TOPOLOGY_LIST_RESTART_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_PHYSICAL_DEVICE_PRIMITIVE_TOPOLOGY_LIST_RESTART_FEATURES_EXT'
--
-- == Version History

--
--     -   Internal revisions
--
-- -   Revision 1, 2021-01-11 (Shahbaz Youssefi)
