* Update release number to 85.
Public Issues:
* Add self-dependency ename:VK_DEPENDENCY_BY_REGION_BIT valid usage
statements for slink:VkSubpassDependency(public pull request 778).
* Apply fix from pull request 742 to slink:VkSubpassDependency and
slink:VkSubpassDependency2 (public pull request 779).
* Specify the units of slink:VkBufferImageCopy::pname:bufferRowLength and
pname:bufferImageHeight as texels (public pull request 781).
* Better specify promoted parameter mapping in the
`<<VK_KHR_create_renderpass2>>` appendix (public pull request 782).
Internal Issues:
* Only include the <<fundamentals-validusage-versions, Valid Usage for
Newer Core Versions>> section in Vulkan 1.1 or later (internal issue
1381).
Other Issues:
* Clean up redundant valid usage language for the
`VK_ANDROID_external_memory_android_hardware_buffer` extension
interaction with slink:VkImageCreateInfo.
* Fix error in a flag name within valid usage statements for
slink:VkMemoryAllocateInfo.
* Clarify that memory types are not totally ordered in
slink:VkPhysicalDeviceMemoryProperties.
* For slink:VkWriteDescriptorSetInlineUniformBlockEXT, set
structextends="VkWriteDescriptorSet" in `vk.xml`, and make
slink:VkDescriptorSetLayoutBindingFlagsCreateInfoEXT::pname:pBindingFlags
optional.
* Add documentation of 'provisional' XML attribute to registry.txt.
New Extensions:
* `VK_NV_compute_shader_derivatives`
* `VK_NV_corner_sampled_image`
* `VK_NV_fragment_shader_barycentric`
* `VK_NV_mesh_shader`
* `VK_NV_representative_fragment_test`
* `VK_NV_scissor_exclusive`
* `VK_NV_shader_image_footprint`
* `VK_NV_shading_rate_image`
* `VK_NVX_raytracing`

This extension adds support for an exclusive scissor test to Vulkan.
|
|
The exclusive scissor test behaves like the scissor test, except that the
|
|
exclusive scissor test fails for pixels inside the corresponding rectangle
|
|
and passes for pixels outside the rectangle.
|
|
If the same rectangle is used for both the scissor and exclusive scissor
|
|
tests, the exclusive scissor test will pass if and only if the scissor test
|
|
fails.

=== Issues
|
|
|
|
1) For the scissor test, the viewport state must be created with a matching
|
|
number of scissor and viewport rectangles.
|
|
Should we have the same requirement for exclusive scissors?
|
|
|
|
*RESOLVED*: For exclusive scissors, we relax this requirement and allow an
|
|
exclusive scissor rectangle count that is either zero or equal to the number
|
|
of viewport rectangles.
|
|
If you pass in an exclusive scissor count of zero, the exclusive scissor
|
|
test is treated as disabled.
