* Update release number to 73.
Github Issues:
* Refine swapchain association with surface for slink:VkSwapchainKHR, with
matching valid usage statements for slink:VkSwapchainCreateInfoKHR and
discussion following the <<swapchain-wsi-image-create-info>> table
(public issue 637).
* Re-remove several valid usage statements from slink:VkImageCreateInfo
that had previously been removed at the time that
ename:VK_IMAGE_CREATE_EXTENDED_USAGE_BIT was introduced. These
statements had incorrectly been restored due to an glitch while merging
from the old `1.0` branch to the current `master` branch (public issue
683).
Internal Issues:
* Fix reference page generation and configure build to generate reference
pages 1.1 with all extensions, rather than core only, as was the case
for the 1.0 ref pages (internal issues 484, 1056, 1205).
* Require that
slink:VkMemoryDedicatedRequirements::pname:prefersDedicateAllocation is
ename:VK_TRUE when
slink:VkMemoryDedicatedRequirements::pname:requiresDedicateAllocation is
ename:VK_TRUE (internal issue 1222).
* Fix Ruby extension code so `diff_html` Makefile target works (internal
issue 1230).
* Update `genRelease` script to generate 1.1 + all extensions reference
pages - but not the single-page HTML / PDF versions, which are even
larger than the API spec (internal issue 1245).
Other Issues:
* Add missing attributes to `vk.xml` for `VK_ANDROID_native_buffer`.
* Specify that the slink:VkAttachmentDescription::pname:format member is
the format of the image *view* that will be used for the attachment.
* Use core sname:VkPhysicalDeviceFeatures2 in the `structextends` `vk.xml`
attribute for sname:VkPhysicalDeviceDescriptorIndexingFeaturesEXT and
sname:VkPhysicalDeviceDescriptorIndexingPropertiesEXT, rather than the
KHR equivalent it was promoted from.
* Fix the "`Fragment Input Attachment Interface`" glossary entry to match
the specification body.
* Clarify the interaction of sRGB images used as storage or texel buffers
with <<textures-output-format-conversion, Texel Output Format
Conversion>>.
* Moved three valid usage statements from
slink:VkRenderPassMultiviewCreateInfo up to
slink:VkRenderPassCreateInfo, and added a new valid usage statement for
slink:VkRenderPassInputAttachmentAspectCreateInfo.
* Added valid usage statements for slink:VkBufferMemoryBarrier and
slink:VkImageMemoryBarrier reflecting the global requirement that
"`non-sparse resources must be bound to memory before being recorded to
command`".
