* Update release number to 112.
Github Issues:
* Clarify that it is possible to use the <<memory-host, Host Memory>>
pname:pfnReallocation callback to free memory in any case that
pname:pfnFree could be used (public issue 973).
Internal Issues:
* Clarify range and precision of code:OpImageQueryLod in the discussion of
scale factor and level-of-detail operation in the
<<textures-normalized-operations, Normalized Texel Coordinate
Operations>> section (internal issues 926, 1719).
* Fix framebuffer layer valid usage statements for
slink:VkRenderPassCreateInfo, slink:VkRenderPassCreateInfo2KHR, and
slink:VkFramebufferCreateInfo (internal issue 1670).
* Refactor common valid usage statements for flink:vkCmdBeginQuery and
flink:vkCmdBeginQueryIndexedEXT (internal issue 1682).
* Prohibit the ename:ename:VK_SAMPLER_YCBCR_RANGE_ITU_NARROW range from
being used in slink:VkSamplerYcbcrConversionCreateInfo for formats with
a bit depth less than 8 (internal issue 1688).
* Add missing interactions with `<<VK_EXT_host_query_reset_usage>>` in the
<<queries, Queries>> chapter (internal issue 1692).
* Clean up error output from the `optimize-pdf` build script on success.
* Fix an internal link to the <<spirvenv-correctly-rounded, Correctly
Rounded>> section in the SPIR-V appendix by adding and referring to that
anchor.
* Fix extension version numbers in `vk.xml` for `VK_EXT_filter_cubic` and
`VK_IMG_filter_cubic`.
* Specify division precision for negative numbers, and remove statement
that trigonometric functions have undefined precision, in the
<<spirvenv-precision-operation, Precision and Operation of SPIR-V
Instructions>> appendix.
* Update release number to 93.
Public Issues:
* Add spec language for ename:VK_INDEX_TYPE_NONE_NV and fix up
slink:VkAccelerationStructureTypeNV (public issue 848).
* Add missing suffix in description of slink:VkSubpassDescription2KHR
parameters (public pull request 851).
* Fix miscellaneous typos (public pull request 855).
* Add driver ID for Pastel (public pull request 856).
* Add missing include directive for slink:VkMemoryWin32HandlePropertiesKHR
implicit valid usage statements (public pull request 857).
Internal Issues:
* Restrict the storage classes permitted for SPIR-V atomics to what is
actually supported, in the <<spirvenv-module-validation, Validation
Rules within a Module>> section (internal issue 1123).
* Add a missing Valid Usage statement to slink:VkRenderPassCreateInfo for
the case pname:stencilLoadOp == ename:VK_LOAD_OP_CLEAR, pname:layout ==
ename:VK_IMAGE_LAYOUT_DEPTH_STENCIL_READ_ONLY_OPTIMAL (internal issue
1408).
* Modify optimize-pdf script and Makefile to retain non-optimized original
PDF on errors (internal issue 1435).
* Add <<spirvenv-module-validation, SPIR-V validation rules>> stating that
only the listed code:BuiltIn decorations are permitted, and only when
relevante features and extensions are enabled (internal issue 1449).
* Remove some duplicated Valid Usage IDs created via cut & paste error
(internal issue 1455).
* Build HTML output for extension reference pages (internal issue 1461).
** Improve genRef.py handling of aliases defined inside other refpages.
** Emit aliases in pygenerator.py.
** Add XML noautovalidity flag for VkRenderPassCreateFlags until there
are some corresponding FlagBits defined.
** Corrected types= attribute on some refpage blocks to 'flags'
** Added refpage blocks for some missing types detected by CI tests.
* Fixed many Valid Usage statement issues in slink:VkRenderPassCreateInfo,
slink:VkSubpassDescription, slink:VkSubpassDescription2KHR,
slink:VkSubpassDependency2KHR, flink:vkCmdBeginRenderPass,
flink:vkCmdBeginRenderPass2KHR, and slink:VkRenderPassBeginInfo
discovered while adding `VK_KHR_create_renderpass2` to the validation
layers.
New Extensions:
* `VK_EXT_scalar_block_layout`
* `VK_EXT_separate_stencil_usage`
associated material at the top level, vk.xml and associated material in
xml/, and generated include and source files in include/vulkan/ and
src/ext_loader/, respectively (public issue 436).
