* Bump API patch number and header version number to 54 for this update.
Github Issues:
Internal Issues:
* Fix tessellation domain to have an upper-left origin in the
<<img-tessellation-topology-ul, tessellation toplogy image>> and related
language. CTS and all implementations were already doing this, it was
just a documentation bug that it was flipped to lower-left (internal
issue 603).
* Add a section to the style guide describing how VUID tags are changed
and removed when the corresponding Valid Usage statements are modified
(internal issue 829).
* Add explicit Valid Usage statement to
slink:VkPipelineDynamicStateCreateInfo to require that members of
pname:pDynamicStates must be unique (internal issue 851).
New Extensions:
* `VK_KHR_16bit_storage`
* `VK_KHR_dedicated_allocation`

|
An application using external memory may wish to synchronize access to that
|
|
memory using fences.
|
|
This extension enables an application to create fences from which non-Vulkan
|
|
handles that reference the underlying synchronization primitive can be
|
|
exported.

=== Issues
|
|
|

<<VK_KHR_external_semaphore,VK_KHR_external_semaphore>>.
|
|
That extension's issues apply equally to this extension.
