--
-- == Description
--
-- This extension enables resources to be bound to a dedicated allocation,
-- rather than suballocated. For any particular resource, applications
-- /can/ query whether a dedicated allocation is recommended, in which case
-- using a dedicated allocation /may/ improve the performance of access to
-- that resource. Normal device memory allocations must support multiple
-- resources per allocation, memory aliasing and sparse binding, which
-- could interfere with some optimizations. Applications should query the
-- implementation for when a dedicated allocation /may/ be beneficial by
-- adding a 'MemoryDedicatedRequirementsKHR' structure to the @pNext@ chain
-- of the
-- 'Vulkan.Core11.Promoted_From_VK_KHR_get_memory_requirements2.MemoryRequirements2'
-- structure passed as the @pMemoryRequirements@ parameter of a call to
-- 'Vulkan.Core11.Promoted_From_VK_KHR_get_memory_requirements2.getBufferMemoryRequirements2'
-- or
-- 'Vulkan.Core11.Promoted_From_VK_KHR_get_memory_requirements2.getImageMemoryRequirements2'.
-- Certain external handle types and external images or buffers /may/ also
-- depend on dedicated allocations on implementations that associate image
-- or buffer metadata with OS-level memory objects.
--
-- This extension adds a two small structures to memory requirements
-- querying and memory allocation: a new structure that flags whether an
-- image\/buffer should have a dedicated allocation, and a structure
-- indicating the image or buffer that an allocation will be bound to.
--
-- == Promotion to Vulkan 1.1
--
-- All functionality in this extension is included in core Vulkan 1.1, with
-- the KHR suffix omitted. The original type, enum and command names are
-- still available as aliases of the core functionality.
--
-- == New Structures
--
-- -   Extending 'Vulkan.Core10.Memory.MemoryAllocateInfo':
--
--     -   'MemoryDedicatedAllocateInfoKHR'
--
-- -   Extending
--     'Vulkan.Core11.Promoted_From_VK_KHR_get_memory_requirements2.MemoryRequirements2':
--
--     -   'MemoryDedicatedRequirementsKHR'
--
-- == New Enum Constants
--
-- -   'KHR_DEDICATED_ALLOCATION_EXTENSION_NAME'
--
-- -   'KHR_DEDICATED_ALLOCATION_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'STRUCTURE_TYPE_MEMORY_DEDICATED_ALLOCATE_INFO_KHR'
--
--     -   'STRUCTURE_TYPE_MEMORY_DEDICATED_REQUIREMENTS_KHR'
--
