18  This extension provides new entry points to query memory requirements of
19  images and buffers in a way that can be easily extended by other extensions,
20  without introducing any further entry points.
21  The Vulkan 1.0 slink:VkMemoryRequirements and
22  slink:VkSparseImageMemoryRequirements structures do not include a
23  pname:sType/pname:pNext, this extension wraps them in new structures with
24  pname:sType/pname:pNext so an application can query a chain of memory
25  requirements structures by constructing the chain and letting the
26  implementation fill them in.
27  A new command is added for each ftext:vkGet*MemoryRequrements command in
28  core Vulkan 1.0.
29

61  === Promotion to Vulkan 1.1
62  
63  All functionality in this extension is included in core Vulkan 1.1, with the
64  KHR suffix omitted.
65  The original type, enum and command names are still available as aliases of
66  the core functionality.
