* 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.
