Description
This extension provides extensible versions of the Vulkan buffer and image copy commands. The new commands are functionally identical to the core commands, except that their copy parameters are specified using extensible structures that can be used to pass extension-specific information.
The following extensible copy commands are introduced with this extension:
vkCmdCopyBuffer2KHR, vkCmdCopyImage2KHR,
vkCmdCopyBufferToImage2KHR, vkCmdCopyImageToBuffer2KHR,
vkCmdBlitImage2KHR, and vkCmdResolveImage2KHR.
Each command contains an *Info2KHR structure parameter that includes
sType/pNext members.
Lower level structures describing each region to be copied are also extended
with sType/pNext members.

Promotion to Vulkan 1.3
Functionality in this extension is included in core Vulkan 1.3, with the KHR suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.
