* Bump API patch number and header version number to 22 for this update.
Github Issues:
* Translate the subpass self-dependency language into concrete
validity statements, and added a validity statement about the
restrictions on layout parameters (public issue 267).
* Add validity requirement that
slink:VkAttachmentDescription::pname:finalLayout and
slink:VkAttachmentReference::pname:layout must not be
ename:VK_IMAGE_LAYOUT_UNDEFINED or
ename:VK_IMAGE_LAYOUT_PREINITIALIZED (public issue 268).
* Clarify that slink:VkSubpassDescription::pname:pResolveAttachments
layouts are used. Make language consistent with other attachment
arrays (public issue 270).
* Changed 64-bit definition for
dname:VK_DEFINE_NON_DISPATCHABLE_HANDLE to work for x32 platform in
+vk.xml+ and the resulting +vulkan.h+ (public issue 282).
* Add missing error return code for
flink:vkEnumerateInstanceExtensionProperties and
flink:vkEnumerateDeviceExtensionProperties (public issue 285)
* Fix several cases of stext::VkStructName.memberName markup to
stext::VkStructName::pname:memberName, to match other usage in the
spec, and describe this markup in the style guide (public issue
286).
* Modified validity language generation script to avoid redundant
common ancestor language if covered by generic parent language, and
used `Both' instead of `Each' when appropriate (public issue 288).
Internal Issues:
* Add language about behavior of flink:vkAllocateDescriptorSets when
allocation fails due to fragmentation, a new error
ename:VK_ERROR_FRAGMENTED_POOL, and a Note explaining the situation
(internal issue 309).
* For the features of code:PointSize, code:ClipDistance, and
code:CullDistance, the SPIR-V capability is required to be declared
on use (read or write) rather than on decoration (internal issue
359).
* Have desktop versions of GLSL respect precision qualification
(code:mediump and code:lowp) when compiling for Vulkan. These will
get translated to SPIR-V's code:RelaxedPrecision decoration as they
do with OpenGL ES versions of GLSL (ESSL). The default precision of
all types is code:highp when using a desktop version (internal issue
360).
* Add validity statement for slink:VkImageCreateInfo specifying that
multisampled images must be two-dimensional, optimally tiled, and
with a single mipmap level (internal issue 369).
* Add validity statements to slink:VkImageViewCreateInfo disallowing
creation of images or image views with no supported features. Made
some slink:VkImageViewCreateInfo validity statements more precise
and consistent. Added a Note to the <<features,features>> chapter
about formats with no features (internal issue 371).
* Remove +manpages+ from default build targets. Nroff outputs
containing imbedded latexmath will not render properly. Fixing this
is a lot of work for limited use cases (internal issue 401).
Other Commits:
* Fix flink:vkRenderPassBeginInfo::pname:clearValueCount validity
statement to be based on attachment indices rather than the number
of cleared attachments
(Vulkan-LoaderAndValidationLayers/issues/601).
* Convert registry documentation from LaTeX to asciidoc source and
rename from +src/spec/readme.tex+ to +src/spec/registry.txt+.
* Fix lack of Oxford commas in validity language.
* Lots of cleanup of generator scripts and Makefiles to move extension
list for generator into the script arguments instead of the body of
genvk.py, and express better dependencies between XML, scripts, and
generated files.
* Bump API patch number and header version number to 21 for this update.
Github Issues:
* Clarify how <<features-supported-sample-counts,sample count queries>>
relate to the limits in slink:VkPhysicalDeviceLimits. (public issue
185).
* Clarify in the <<interfaces-iointerfaces,Shader Input and Output
Interfaces>> section that shader output variables have undefined values
until the shader writes to them (public issue 240).
* Specify the implicit value of image parameters that cannot be set in
slink:VkSwapchainCreateInfo::pname:flags, pname:imageType,
pname:mipLevels, pname:samples, pname:tiling, and pname:initialLayout
(public issue 243).
* Make use of code:NULL and code:VK_NULL_HANDLE consistent in the
VK_KHR_swapchain extension (public issue 276).
Internal Issues:
* Clarify that presenting an image to a display surface swapchain applies
the display surface's mode, and that destroying a display surface
swapchain may reset the display's mode, in the VK_KHR_display_swapchain
extension (internal issue 247).
* Better describe what a slink:VkSurfaceKHR is, and that creating one does
not set a mode, in the VK_KHR_display extension. This is a round-about
way of pointing out that mode setting is not covered by the extension,
but rather is performed as a side effect of presentation (internal issue
247).
* Add more valid usage statements to flink:vkQueuePresentKHR command when
the VK_KHR_display_swapchain extension is present (internal issue
247).
* Add more includes to the VK_KHR_swapchain extension to better document
interactions with VK_KHR_display_swapchain (internal issue 247).
* Clarify restrictions on location aliasing in the
<<fxvertex,Fixed-Function Vertex Processing>> section (internal issue
370).
* Add mathematical description of blitting to flink:vkCmdBlitImage, and
link it to the <<textures,Image Operations>> chapter. Use mathematical
notation for ranges of texel coordinates in the <<textures,Image
Operations>> chapter. Fixed miscellaneous validity statements for
flink:vkCmdBlit and slink:VkImageBlit (internal issue 382).
Other Commits:
* Added a valid usage rule to flink:VkGraphicsPipelineCreateInfo that the
ename:VK_PRIMITIVE_TOPOLOGY_PATCH_LIST topology must only be used when
tessellation shaders are used.
* Expand the style guide into a formal "Procedures and Conventions"
document. Add a API Naming Conventions section, move most of the API
Specification Appendix C (Layers and Extensions) content into the new
document, and define the resulting procedures as mandatory (where
relevant). This more clearly separates use vs. specification of Vulkan
APIs.
* Update vk_platform.h to handle 32-bit ARMv8 binaries.
* Various minor cleanups to the Makefile and build process.
* Bump API patch number and header version number to 20 for this
update.
Github Issues:
* Replaced existing reference pages by text automatically extracted
from the specification source, or generated from vk.xml in some
cases. This isn't a complete solution for the reference pages, but
puts them in a much better state. The ref pages (only) are now
placed under a CC BY open source license, which is more current than
the obsolete license previously used.
Further improvements to the pages should not edit them directly, but
instead concentrate on the specification source from which the ref
pages are being extracted (public issues 44, 55, 160; internal issue
389).
* Bump API patch number and header version number to 18 for this
update.
Github Issues:
* Added "queue operation" terminology, and modified spec to actually
use this terminology (public issue 155). The act of submitting a
piece of work to a queue now generates "operations" for the queue to
execute, including operations to wait on/signal semaphores and
fences. Synchronization waits on these operations, making execution
dependency chains more obvious for semaphores and fences (though
additional work is still needed here). These changes include:
** Overview of "queue submission" commands in chapter
<<devsandqueues-submission>>.
** Updated descriptions for fence and semaphore waits and signals in
the synchronization chapter <<synchronization-semaphores-waiting>>,
<<synchronization-semaphores-signaling>> and
<<synchronization-fences-waiting>>.
** Clarifications to semaphore and fence operation within queue
submission functions.
** New glossary terms.
** Moved device idle and queue wait idle to synchronization chapter in
order to describe them in terms of other synchronization
primitives.
** Clarifications to semaphore and fence operation allowed removal of
the "implicit ordering guarantees" section, as this information is
now wholly covered where these primitives are described.
*** The "host writes" section of this is still there for now - in its
own section. This could probably be merged into other sections
later.
*** Modified fundamentals chapter on queue ordering to make sense in
context of the new changes, and avoid duplication.
<<fundamentals-queueoperation>>
* Added "aspect" and "component" definitions to the glossary, and made
sure these terms are referenced correctly (public issue 163).
* Update valid usage for ftext:vkGet*ProcAddr to only include
conditions that must be met to get a valid result. In particular,
it's okay to call flink:vkGetDeviceProcAddr with any string and will
get a code:NULL if that string is not a core Vulkan function or an
enabled extension function (addresses but does not fully close
public issue 214).
* Change the WSI extension dependencies to refer to version 1.0 of the
Vulkan API, instead of the pre-1.0-release internal revisions
numbers (public issue 238).
* Specified that <<interfaces-fragmentoutput,undeclared fragment
shader outputs>> result in undefined values input to the blending
unit or color attachment (public issue 240).
Internal Issues:
* Better documented that the registry XML "optional" tag for values
only applies when that value is the size of an array (internal issue
335).
* Add a stronger definition for the valid usages of
VkSpecializationMapEntry.size in the
<<pipelines-specialization-constants,Specialization Constants>>
section (internal issue 345).
* Change code:OpName to code:OpDecorate (along with appropriate
syntax) for vertex shader built-ins (internal issue 368).
* Add missing ref pages (those which are not currently stubs) to
apispec.txt for the single-page version of the ref pages (internal
issue 378).
Other Commits:
* Fix example in the <<descriptorsets,Descriptor Sets>> section to use
M, N, and I, describing set, binding, and index, consistently
throughout the example code.
* Bump API patch number and header version number to 17 for this
update.
Github Issues:
* Update description of vertex shader reuse in
<<shaders-vertex-execution>> (public issue 106).
* Simplify validity language around pname:ppEnabledExtensionNames and
pname:ppEnabledLayerNames (in the <<initialization-instances>> and
<<devsandqueues-device-creation>> sections) (public issue 214).
* Add missing validity rule to flink:vkCmdBeginRenderPass requiring
compatibility between slink:VkAttachmentDescription pname:initalLayout
members and the corresponding attached framebuffer images (public issue
233).
* Fix Unicode arrows appearing in output instead of relational operators
(public issue 239).
* Correctly describe the required number of elements for
code:TessLevelInner and code:TessLevelOuter arrays in the
<<interfaces-builtin-variables,Built-In Variables>> section as two and
four, respectively, instead of the other way around, and refer to this
section from the <<tessellation,Tessellation>> chapter (public issue
246).
Internal Issues:
* Document deprecation of ename:VK_COLORSPACE_SRGB_NONLINEAR_KHR in the
VK_KHR_surface extension branch, and of
ename:VK_STRUCTURE_TYPE_DEBUG_REPORT_CREATE_INFO_EXT in the
VK_EXT_debug_report branch (internal issue 328).
* Added language to define what a valid usage statement is and should be,
with a note about some apparent weirdnesses this might entail (internal
issue 357).
Other Commits:
* Added missing ename:VK_ERROR_DEVICE_LOST error to
flink:vkQueueBindSparse.
* Bump API patch number and header version number to 13 for this
update.
Github Issues:
* Improve the description of ename:VK_PRESENT_MODE_FIFO_RELAXED_KHR in the
VK_KHR_surface extension (public issue 174).
* Clarify use of etext:*_SIMULTANEOUS_USE_BIT for secondary command
buffers (public issue 182).
* Fix typos in VK_KHR_wayland_surface extension where code:wl_device was
used instead of code:wl_display (public issue 193).
* Replaced {apiname} with ``Vulkan'' in XML validity statements (public
issue 199).
* Fix dead links for WSI handle types (public issue 200).
*** N.b. this needs to be done in WSI branches as well ***
* Use "signaled" instead of "signalled" spelling everywhere (public issue
201).
*** N.b. this needs to be done in WSI branches as well ***
* Move readme.pdf target directory for XML schema documentation into the
target generation directory, instead of leaving it checked into the spec
source tree (public issue 203).
*** N.b. need to add generated PDF to registry index/1.0 page
* Fix duplicate 'which which' typo in description of
elink:VkCommandPoolResetFlagBits (public issue 204).
* Move the <<Programmable Primitive Shading>> section up one level, out of
the <<drawing-primitive-topologies,Primitive Topologies>> section
(public issue 209).
Internal Issues:
* Clarify in the <<pipelines-cache,Pipeline Cache>> section that
implementations should not manage the size of pipeline cache (internal
issue 192).
* Deprecate the concept of device layers and associated commands (internal
issue 255).
* Remove ename:VK_INCOMPLETE from the list of possible result codes of
flink:vkGetPhysicalDeviceSurfaceCapabilitiesKHR (internal issue 314).
* Add missing std140/std430 rule: the base alignment of a member following
a structure is a multiple of the structure's base alignment (internal
issue 321).
* Fixes naming of the single elink:VkColorSpaceKHR enum from
ename:VK_COLORSPACE_SRGB_NONLINEAR_KHR to
ename:VK_COLOR_SPACE_SRGB_NONLINEAR_KHR in XML/header and the
VK_KHR_swapchain and VK_KHR_surface extensions to match the style of the
typename (space and color are two words, not one) (internal issue 322).
* Make it clear that code:LocalInvocationID should only be applied to an
input variable and normalize the language describing
code:LocalInvocationID to the language for other compute shader
variables in the <<interfaces-builtin-variables,Built-in Variables>>
section, and add normative language (internal issue 323).
* Clarify in the <<fundamentals-returncodes,Return Codes>> section that
the result pointer may be modified for specific commands, even if a
runtime error is returned (internal issue 324).
* Bump API patch number and header version number to 12 for this
update.
Github Issues:
* Change valid usage statements intended to be "sub-points" to
be actual sub-points (public issue 66).
* Replace double negation in description of
slink:VkRenderPassBeginInfo::pname:pClearValues (based on public
merge 142).
* Cleanup minor typos in spec, ref pages and XML, including those
proposed in public pull requests 144, 150, 151, 167, 168, 181, and
186.
* Use *strict subset* in describing the partial order of memory
property types for slink:VkMemoryType, and update the style guide
accordingly (public issue 190).
* Fix various "a image" -> "an image" typos (public issue 191).
* Note in the <<fundamentals-validusage,Valid Usage>> and
<<extensions-interactions,Extension Interactions>> sections that
structures defined by extensions which may be passed in structure
chains using the ptext:pNext member must: include initial
ptext:sType and ptext:pNext members (public issue 192).
Internal Issues:
* Remove duplicate language from the description of the pname:fence
parameter to flink:vkQueueSubmit and improve validity language
(internal issue 91).
* Added documentation for "optional" attribute to XML readme.tex/pdf
(internal issue 149).
* Clarify the host-side data validity rules and behavior of
flink:vkFlushMappedMemoryRanges and
flink:vkInvalidateMappedMemoryRanges (internal issue 266).
Other Commits:
* Added clarification to flink:vkCmdFillBuffer regarding the use of
ename:VK_WHOLE_SIZE.
* Fixed and documented implementation of "validextensionstructs"
attribute. in XML processing scripts and readme.tex/pdf.
* Add missing validity statements to flink:vkResetEvent and
flink:vkCmdResetEvent.
* Fix validity for the
ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT flag.
Correct all the draw/dispatch commands to mention optimally tiled
images as well as linear tiled images, and say image VIEWS instead
of images. Add validity statement to flink:vkCmdBlitImage
* Replace the {apiname} macro with hardcoded "Vulkan", now that we've
committed to that name.
* Add the VK_AMD_rasterization_order extension to vk.xml.
* Bump API patch number and header version number to 11 for this
update.
Github Issues:
* Clarify the WSI extension language by switching from the fuzzier
"ownership" language to more-consistent "acquire" language (public
issue 117).
* Clarify that memory barriers apply to all commands in the dependency
chains in the flink:vkGetRenderAreaGranularity command and the
<<synchronization-execution-and-memory-dependencies,Execution And
Memory Dependencies>> section (public issue 132).
* Clarify that a queue family is a set of queues in the
<<fundamentals-execmodel,Execution Model>> section (public issue
166).
* Removed requirement from valid usage language that
VkPresentInfoKHR::waitSemaphoreCount must be greater than 0 (public
issue 171).
* Fix broken internal links, describe structures consistently, use
consistent style for SPIR-V codewords, and tag normative terms that
were missing asciidoc tags (public issue 183 and ancillary
markup/normative language fixes).
* Fix typos for slink:VkPhysicalDeviceLimits member names in
slink:VkImageCreateInfo validity language (public issue 184).
Internal Issues:
* Document that the requested patch version number specified as part
of slink:VkApplicationInfo::pname:apiVersion is ignored when
creating an instance (internal issue 176).
* Clarify handling of extension structs in the
<<fundamentals-validusageValid Usage>> section (internal issue 254).
* Update required slink:VkImageFormatProperties::pname:maxMipLevels to
be limited to the maximum allowed mipmap pyramid size corresponding
to the actual maximum supported size for the format (internal issue
256).
* Modify the <<features-extentperimagetype,Allowed Extent Values Based
On Image Type>> section so the allowed maximum extent is the maximum
image dimension supported for each dimension of the type of texture
being queried (internal issue 257).
* Clarify in the <<spirvenv-module-validation,Validation Rules within
a Module>> section that at least one of the code:LocalSize execution
mode or code:WorkgroupSize decoration is required for each compute
shader entry point in a shader module (internal issue 279).
* Add validity rules for formats in flink:vkCmdClearColorImage and
flink:vkCmdClearDepthStencilImage (internal issue 283).
* Clarify that slink:VkImageFormatProperties::pname:maxResourceSize is
an upper bound, and that it may not be possible to create an image
anywhere near that size (internal issue 284).
Other Commits:
* Fix various minor markup errors reported by validation scripts.
* Change copyright from Khronos Free Use License to Apache 2.0 license
on relevant script/XML/header files. This does not affect the
specification source copyright.
* Bump API patch number and header version number to 10 for this
update.
Github Issues:
* Slightly tweak the <<memory-allocation,Host Memory>> allocator language
so that an application wrapping the standard C alloc/free/realloc
functions is still correct - the previous language was too strong with
regards to freeing memory. Also made certain scenarios clearer - an
implementation may now continue without error if an allocation failed
and it is able to continue correctly (public issue 21).
* Require that etext:VK_*_CREATE_SPARSE_BINDING_BIT is set when the
corresponding etext:VK_*_CREATE_SPARSE_RESIDENCY_BIT is used, in the
<<sparsememory-miptail,Mip Tail Regions>> section and related commands
flink:vkCreateBuffer and flink:vkCreateImage (public issue 84).
* Update the <<features,Features, Limits, and Formats>> chapter to clarify
interactions between optional features and dynamic state for the
pname:depthBiasClamp and pname:wideLines features (public issue 89).
* Describe the code:WorkgroupSize builtin in the
<<interfaces-builtin-variables,Built-In Variables>> section, and update
the <<compute-shaders,Compute Shaders>> section to further clarify how
to set the number of workgroups to execute in a compute shader (public
issue 145).
* Use the term *image subresource* everywhere instead of *subresource*,
except for the special case of *host-accessible subresource*, which may
be either an image subresource or buffer range (public issue 120)
* Add a note to the <<features,Features, Limits, and Formats>> section
about extensibility of structures (Public issue 165).
* Fix return code flink:vkAcquireNextImageKHR when the timeout parameter
is 0 to ename:VK_NOT_READY instead of ename:VK_TIMEOUT (public issue
170).
* Fix typo in slink:VkLayerProperties::pname:apiVersion field (public
issue 172).
Internal Issues:
* Fix a few minor internally-detected typos.
* Minor formatting tweaks to pseudocode in the <<resources,Resource
Creation>> chapter (internal issue 179).
* Fix typo in the definition of point sampling for
elink:VkCullModeFlagBits (internal issue 268).
* Bump API patch number and header version number to 7 for this
update.
Github Issues:
* Fix slink:VkSpecializationMapEntry example to avoid C/C++ strict
aliasing issues (public issue 14).
* Clarify the meaning of "matching" in flink:vkCmdBindDescriptorSets
validity language (public issue 33).
* Add stub reference pages so xrefs to not-yet-written pages don't
generate 404 errors. However, the actual content of these pages
still needs to be filled in as time allows (public issue 44, but
does not close that issue out).
* Remove incorrect validity statement for
flink:vkGetImageSparseMemoryRequirements (public issue 85).
* Reword the
<<features-limits-bufferImageGranularity,bufferImageGranularity>>
feature in terms of "aliasing", and clarify that it applies to
bindings in the same memory object (public issue 90).
* Clarify the relationship of the slink:VkPhysicalDeviceLimits
pname:maxViewportDimensions and pname:viewportBoundsRange limits
(public issue 92).
* Specify sparse unbound texture replacement in the
<<textures-texel-replacement,Texel Replacement>> section
independently of robust buffer access language (public issue 100).
* Add the <<fundamentals-architecture-model,Architecture Model>>
section to explain architecture constraints Vulkan has chosen to
accept in order to enable portable and performant code (public issue
122).
* State that an object must not be destroyed until *all* (not *any*)
uses of that object have completed (public issue 123).
* Minor editorial cleanup (public issues 129, 134, 146, 148).
* Add validity language for layer and extension names to
slink:VkDeviceCreateInfo matching that used for
slink:VkInstanceCreateInfo (public issue 130).
* Clean up terminology for the case when the bits set in one bitmask
are a subset of the bits set in another bitmask (public issue 138).
* Document that input attachments are UniformConstant not Input, in
the <<interfaces-inputattachment,Fragment Input Attachment
Interface>> section (public glslang bug 169).
Internal Issues:
* Add max enum values to "flag bits" enums (internal issue #136).
* Clarify language around the various uses of the term "block" in the
<<appendix-compressedtex-bc,Block Compressed Image Formats>> section
(internal issue #202).
* Removed "expand" dependency from <enums> groups in vk.xml and added
auto-generation code in the scripts to infer it instead, to ensure
consistency. This caused renaming of sname:VkColorSpaceKHR and
sname:VkPresentModeKHR etext:BEGIN_RANGE (etc.) tokens, but those
tokens are metadata, not part of the API, and the Vulkan WG is OK
with this change. This change adds ranges to two additional enums
that were missing them due to not defining the "expand" attribute
(internal issue 217).
* Tweak makefile to generate ref page nroff (.3) files in the right
output directory, working around an a2x limitation (internal issue
223).
Other Commits:
* Add validity requirements for flink:vkCmdCopyQueryPoolResults
pname:dstBuffer parameter.
* Fix ref page build to generate .3 targets in the right output
directory.
* Bump API patch number to 5 for this update.
Github Issues:
* Correctly describe slink:VkPhysicalDeviceProperties pname:deviceName
member as a string, not a pointer to a string. Also one typo fix for
"hetereogeneous" (public issue 4).
* Replace maynot: macro with may: not, and "may: or maynot:" with
"may:" (public issue 4).
* Clarify that redundantly setting the state of a fence or event has
no effect (public issue 4).
* Minor fixes to ref pages to track descriptions of memory bits that
changed in the core spec. Fix name of a member in the description of
sname:sname:VkPipelineMultisampleStateCreateInfo (public issues 8,
13).
* Remove redundant validity statement for
sname:VkGraphicsPipelineCreateInfo::pname:stageCount (public issue
14).
* Fix typos in chapters 7-9 (public issue 14).
* Clarify the example demonstrating the behavior of
code:OpMemoryBarrier in the
<<shaders-execution-memory-ordering,shader memory acces
ordering>> section (public issue 16).
* Specify that freeing mapped memory implicitly unmaps the memory in
the description of flink:vkFreeMemory (public issue 17).
* Forbid allocation callbacks from calling into the API in the
<<memory-allocation,memory allocation>> section (public issue
20).
* Add missing validity rules about size being greater than 0 and
offset being less than size of object. Fix
flink:VkMappedMemoryRange's misinterpretation of offset (public
issues 27, 31).
* Add validity rule disallowing overlapping source/destination
descriptors in flink:VkCopyDescriptorSet (public issue 32).
* Clarify that array and matrix stride has to be a multiple of the
base alignment of the array or matrix in the
<<interfaces-resources-layout,Offset and Stride Assignment>>
section (public issue 38).
* Correct parenthesis floor nesting error in equation for
<<textures-RGB-sexp,RGB to shared exponent conversion>>.
Clarify case of when exp' is forced to 0, avoiding log2(0) undefined
problem (public issue 40).
* Remove redundant statement from the code:FragDepth description in
the <<interfaces-builtin-variables,Built-In Variables>>
section (public issue 47).
* Define the clamping of the
<<textures-level-of-detail-operation,bias added to the scale
factor>> by linking to the slink:VkPhysicalDevice feature
pname:maxSamplerLodBias (public issue 64).
* Fix typo "optimal linear resources" and clarify the set of resources
<<features-limits-bufferImageGranularity,the
pname:bufferImageGranularity resource>> applies to (public issue
67).
* Replace 'descriptor accessed by a pipeline' language for
sname:VkDescriptorSetAllocateInfo with more precise phrasing about
binding a descriptor set before a command that invokes work using
that set (public issue 69).
* tstripadj.svg contained an Inkscape tag which caused Firefox and IE
11 to fail to render it, and was illegal SVG. Generating Plain SVG
from the Inkscape SVG source fixes this (public issue 70).
* Fix validity for sname:VkVertexInputBindingDescription and
sname:VkVertexInputAttributeDescription numbers (public issue 72).
Internal Issues:
* Clarify the meaning of
ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT in
elink:VkFormatFeatureFlagBits with respect to depth compare
(internal issue 107).
* Added a note explaining that ename:VK_QUEUE_TRANSFER_BIT may or may
not be reported for a queue family that already supports
ename:VK_QUEUE_GRAPHICS_BIT or ename:VK_QUEUE_COMPUTE_BIT as the
former is a strict subset of the latter ones (internal issue 116).
* Add validity language for sname:VkDescriptorSetAllocateInfo about
exceeding the descriptor pool capacity (internal issue 140).
* Add ename:VK_INCOMPLETE success code for
flink:vkEnumeratePhysicalDevices query (internal issue 163).
Other Commits:
* Add the VK_NV_glsl_shader extension definitions to the API.
* Update GL_KHR_vulkan_glsl with 1) origin_upper_left as default 2)
specialization array constant semantics.
* Corrected/updated Data Format Specification date.
