* Update release number to 124.
Github Issues:
* Fix Makefile SPECREMARK macro to work when not building in a git tree
(public issue 992).
* Ignore pname:aspectMask for unused attachments in
slink:VkSubpassDescription2KHR valid usage statements (public pull
request 1028).
* Minor markup / spelling fixes (public pull requests 1035, 1045).
Internal Issues:
* Fix markup in Valid Usage statement for slink:VkCreateFramebuffer
(internal issue 1823).
* Add a new <<synchronization-signal-operation-order, _signal operation
order_>> section to the synchronization chapter which describes in
detail the ordering guarantees provided by the API between fence and
semaphore signal operations (internal merge request 3368).
* Move generated `appendix/meta/` files into the Makefile GENERATED
directory (internal merge request 3381).

This extension adds support for the following SPIR-V extension in Vulkan:
|
|
|
|
* `SPV_NV_sample_mask_override_coverage`
|
|
|
|
The extension provides access to the code:OverrideCoverageNV decoration
|
|
under the code:SampleMaskOverrideCoverageNV capability.
|
|
Adding this decoration to a variable with the code:SampleMask builtin
|
|
decoration allows the shader to modify the coverage mask and affect which
|
|
samples are used to process the fragment.
|
|
|
|
When using GLSL source-based shader languages, the code:override_coverage
|
|
layout qualifier from `GL_NV_sample_mask_override_coverage` maps to the
|
|
code:OverrideCoverageNV decoration.
|
|
To use the code:override_coverage layout qualifier in GLSL the
|
|
`GL_NV_sample_mask_override_coverage` extension must be enabled.
|
|
Behavior is described in the `GL_NV_sample_mask_override_coverage` extension
|
|
spec.
