* 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`
* `VK_KHR_external_fence`

The +VK_KHR_16bit_storage+ extension allows use of 16-bit types in shader
|
|
input and output interfaces, and push constant blocks.
|
|
This extension introduces several new optional features which map to SPIR-V
|
|
capabilities and allow access to 16-bit data in code:Block-decorated objects
|
|
in the code:Uniform and the code:StorageBuffer storage classes, and objects
|
|
in the code:PushConstant storage class.
|
|
This extension allows 16-bit variables to be declared and used as
|
|
user-defined shader inputs and outputs but does not change location
|
|
assignment and component assignment rules.
