* Update release number to 82.
Public Issues:
* Add flink:vkDestroyPipelineLayout valid usage statement that the layout
must not have been used with command buffers still in the recording
state (public issue 730).
* Correct \<unused> tag for elink:VkResult in `vk.xml` (public merge
request 746).
Internal Issues:
* Add a valid usage statement to flink:vkQueueSubmit, and similar language
to the definitions of <<synchronization-queue-transfers-acquire, acquire
operations>> requiring that an acquire operation follow a previous
release of the same subresource (internal issue 1290).
* Add <<resources-image-format-features,Image Format Features>> and
<<resources-image-view-format-features,Image View Format Features>>
sections that precisely define the slink:VkFormatFeatures supported by
images and image views, and rewrite valid usage statements to reference
these sections instead of duplicating language (internal issue 1310).
* Reword and consolidate synchronization valid usage statements for
flink:vkCmdPipelineBarrier such that they correctly account for mutiple
possible self-dependencies (internal issue 1322).
* Change order of <<Standard sample locations>> for 2xMSAA (internal issue
1347).
* Add definitions of "`<<Correctly Rounded>>`" and "`<<ULP>>`" in the
SPIR-V environment appendix, and "`Units in the Last Place (ULP)`" in
the glossary.
New Extensions:
* `VK_NV_device_diagnostic_checkpoints`
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).
