Change log for December 16, 2016 Vulkan 1.0.38 spec update:
* Bump API patch number and header version number to 38 for this update.
Github Issues:
* Make ename:VK_PIPELINE_STAGE_HOST_BIT invalid for all stage masks,
except for flink:vkCmdWaitEvents (public issue 261).
Internal Issues:
* Added validation language for flink:vkQueueBindSparse,
slink:VkPresentInfoKHR, and slink:VkSubmitInfo, and a note to the
<<synchronization-semaphores-waiting,Semaphore Waiting and Unsignaling>>
section to clarify that semaphores must be signaled and waited on in a
1:1 fashion (internal issue 546).
* Modify valid usage for slink:VkBufferImageCopy to only require
pname:bufferOffset to be a multiple of the image format's element size
when the format is not depth/stencil (internal issue 594).
Other Issues:
* Vulkan(R) is now a registered trademark symbol, and this is reflected in
documents and copyright statements.

[NOTE]
|

====
|

Unlike fences or events, the act of waiting for a semaphore also unsignals
|

that semaphore.
|

If two operations are separately specified to wait for the same semaphore,
|

and there are no other execution dependencies between those operations,
|

behaviour is undefined.

An execution dependency must: be present that guarantees that the semaphore

unsignal operation for the first of those waits, happens-before the
|
||||
semaphore is signalled again, and before the second unsignal operation.
|
||||
Semaphore waits and signals should thus occur in discrete 1:1 pairs.
