* Update release number to 96.
Public Issues:
* Fix typo in `vk.xml` for `structextends` attribute of
slink:VkPhysicalDeviceShadingRateImagePropertiesNV (public PR 870).
* Fix links in optimized PDF output (public PR 879).
Internal Issues:
* Add a link to GitHub contributors in the <<credits, Other Credits>>
section (internal issue 808).
* Clarify the behavior of command aliases described in the <<versions,Core
Revisions>> and <<initialization-functionpointers, Command Function
Pointers>> sections and the registry schema document with respect to
whether they are or are not the same entry point, and what the behaviour
of the ftext:vkGet*ProcAddr commands is for each alias (internal issue
1462).
* Update slink:VkPipelineShaderStageCreateInfo valid usage statements for
writing to code:Layer and code:viewportIndex to apply to any vertex
processing stage (internal issue 1475).
* Make sparse image creation optional for Y'C~B~C~R~ formats in the
<<features-required-format-support, Required Format Support>> section
and the <<features-formats-requiring-sampler-ycbcr-conversion, Formats
requiring sampler Y'C~B~C~R~ conversion for
ename:VK_IMAGE_ASPECT_COLOR_BIT image views>> table (internal issue
1476).
* Modify the valid usage statement for
flink:vkCmdDrawIndirectByteCountEXT::pname:vertexStride to use the
pname:maxTransformFeedbackBufferDataStride limit rather than the
pname:maxVertexInputBindingStride limit, which is a better match for
transform feedback related operations (internal issue 1487).
* Changed all members of slink:VkPhysicalDevicePCIBusInfoPropertiesEXT to
have the `uint32_t` type. This is an imcompatible change to an EXT
that's very recently released; although this is against usual Vulkan WG
policy, we discussed and consider this an acceptable risk, but have
polled the mesa-dev list in case there are use cases we missed (internal
issue 1492).
* Set spec vetsion to 1 for `VK_GOOGLE_hlsl_functionality1` and
`VK_GOOGLE_decorate_string` in `vk.xml` (internal MR 2948).
* Remove redundant valid usage statement `VkImageCreateInfo-pNext-02395`
(internal MR 2950).
* Add `check_spec_links.py` script, use it in Gitlab CI, and fix many
minor markup issues discovered by the script (internal MR 2955).
* Update `BUILD.md` to the current Ruby version (2.5.3), and make some
corresponding updates to per-platform build instructions (internal MR
2956).
* Fix binding numbers and other details in
flink:vkUpdateDescriptorSetWithTemplate.txt example code blocks
(internal MR 2960).
* Remove some nautovalidity="true" in `vk.xml` for NV extensions where
it's clearly wrong (internal MR 2970).

This extension provides additional orthogonally aligned "`discard
|
|
rectangles`" specified in framebuffer-space coordinates that restrict
|
|
rasterization of all points, lines and triangles.
|
|
|
|
From zero to an implementation-dependent limit (specified by
|
|
pname:maxDiscardRectangles) number of discard rectangles can be operational
|
|
at once.
|
|
When one or more discard rectangles are active, rasterized fragments can
|
|
either survive if the fragment is within any of the operational discard
|
|
rectangles (ename:VK_DISCARD_RECTANGLE_MODE_INCLUSIVE_EXT mode) or be
|
|
rejected if the fragment is within any of the operational discard rectangles
|
|
(ename:VK_DISCARD_RECTANGLE_MODE_EXCLUSIVE_EXT mode).
|
|
|
|
These discard rectangles operate orthogonally to the existing scissor test
|
|
functionality.
|
|
ifdef::VK_VERSION_1_1,VK_KHR_device_group[]
|
|
The discard rectangles can be different for each physical device in a device
|
|
group by specifying the device mask and setting discard rectangle dynamic
|
|
state.
