-- | VkSharingMode - Buffer and image sharing modes
--
-- = Description
--
-- Note
--
-- 'SHARING_MODE_CONCURRENT' /may/ result in lower performance access to
-- the buffer or image than 'SHARING_MODE_EXCLUSIVE'.
--
-- Ranges of buffers and image subresources of image objects created using
-- 'SHARING_MODE_EXCLUSIVE' /must/ only be accessed by queues in the queue
-- family that has /ownership/ of the resource. Upon creation, such
-- resources are not owned by any queue family; ownership is implicitly
-- acquired upon first use within a queue. Once a resource using
-- 'SHARING_MODE_EXCLUSIVE' is owned by some queue family, the application
-- /must/ perform a
-- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#synchronization-queue-transfers queue family ownership transfer>
-- to make the memory contents of a range or image subresource accessible
-- to a different queue family.
--
-- Note
--
-- Images still require a
-- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#resources-image-layouts layout transition>
-- from 'Vulkan.Core10.Enums.ImageLayout.IMAGE_LAYOUT_UNDEFINED' or
-- 'Vulkan.Core10.Enums.ImageLayout.IMAGE_LAYOUT_PREINITIALIZED' before
-- being used on the first queue.
--
-- A queue family /can/ take ownership of an image subresource or buffer
-- range of a resource created with 'SHARING_MODE_EXCLUSIVE', without an
-- ownership transfer, in the same way as for a resource that was just
-- created; however, taking ownership in this way has the effect that the
-- contents of the image subresource or buffer range are undefined.
--
-- Ranges of buffers and image subresources of image objects created using
-- 'SHARING_MODE_CONCURRENT' /must/ only be accessed by queues from the
-- queue families specified through the @queueFamilyIndexCount@ and
-- @pQueueFamilyIndices@ members of the corresponding create info
-- structures.
