-- for the specified image subresource range, and the first access scope
-- includes no access, as if @srcAccessMask@ was @0@.
--
-- If @oldLayout@ is not equal to @newLayout@, then the memory barrier
-- defines an
-- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#synchronization-image-layout-transitions image layout transition>
-- for the specified image subresource range.
--
-- Layout transitions that are performed via image memory barriers execute
-- in their entirety in
-- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#synchronization-submission-order submission order>,
-- relative to other image layout transitions submitted to the same queue,
-- including those performed by
-- <https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/vkspec.html#renderpass render passes>.
-- In effect there is an implicit execution dependency from each such
-- layout transition to all layout transitions previously submitted to the
-- same queue.
--
-- The image layout of each image subresource of a depth\/stencil image
-- created with
-- 'Vulkan.Core10.Enums.ImageCreateFlagBits.IMAGE_CREATE_SAMPLE_LOCATIONS_COMPATIBLE_DEPTH_BIT_EXT'
-- is dependent on the last sample locations used to render to the image
-- subresource as a depth\/stencil attachment, thus when the @image@ member
-- of a 'ImageMemoryBarrier' is an image created with this flag the
-- application /can/ include a
-- 'Vulkan.Extensions.VK_EXT_sample_locations.SampleLocationsInfoEXT'
-- structure in the @pNext@ chain of 'ImageMemoryBarrier' to specify the
-- sample locations to use during the image layout transition.
--
-- If the
-- 'Vulkan.Extensions.VK_EXT_sample_locations.SampleLocationsInfoEXT'
-- structure included in the @pNext@ chain of 'ImageMemoryBarrier' does not
-- match the sample location state last used to render to the image
-- subresource range specified by @subresourceRange@ or if no
-- 'Vulkan.Extensions.VK_EXT_sample_locations.SampleLocationsInfoEXT'
-- structure is included in the @pNext@ chain of 'ImageMemoryBarrier', then
-- the contents of the given image subresource range becomes undefined as
-- if @oldLayout@ would equal
-- 'Vulkan.Core10.Enums.ImageLayout.IMAGE_LAYOUT_UNDEFINED'.
--
-- If @image@ has a multi-planar format and the image is /disjoint/, then
-- including
-- 'Vulkan.Core10.Enums.ImageAspectFlagBits.IMAGE_ASPECT_COLOR_BIT' in the
-- @aspectMask@ member of @subresourceRange@ is equivalent to including
-- 'Vulkan.Core10.Enums.ImageAspectFlagBits.IMAGE_ASPECT_PLANE_0_BIT',
-- 'Vulkan.Core10.Enums.ImageAspectFlagBits.IMAGE_ASPECT_PLANE_1_BIT', and
