Change log for October 6, 2017 Vulkan 1.0.62 spec update:
* Bump API patch number and header version number to 62 for this update.
Github Issues:
* Move asciidoc conditionals for `VK_KHR_maintenance1` in
slink:VkDescriptorSetAllocateInfo so valid usage statements for
`VK_KHR_push_descriptor` aren't accidentally removed when the first
extension isn't enabled (public issue 573).
* Fixed errors in API example code for
flink:vkUpdateDescriptorSetWithTemplateKHR and
flink:vkCmdPushDescriptorSetWithTemplateKHR (public issue 577).
Internal Issues:
* Specify constraints on concurrent access to fences that share payload in
the <<synchronization-fences-importing, Importing Fence Payloads>> and
<<synchronization-semaphores-waiting-state, Semaphore State Requirements
For Wait Operations>> sections (internal issue 820).
* Define the term "`retired swapchain`", reorganize some swapchain
language, and improve language for pname:oldSwapchain in
flink:VkSwapchainCreateInfoKHR, the <<swapchain-wsi-image-create-info>>
table, flink:vkDestroySwapchainKHR, and flink:vkAcquireNextImage2KHX
(internal issue 869).
* Describe in the <<writing-arrays, Describing Properties of Array
Elements>> section of the style guide how and when to use "`each`" and
"`any`" to refer to properties of array elements, and make those uses in
the specification consistent (internal issue 884).
* Clarified that events cannot be used for cross-queue synchronization in
the <<synchronization-events, Events>> section and for
flink:vkCmdWaitEvents (internal issue 970).
* Add success and error codes to +vk.xml+ for
flink:vkCreateValidationCacheEXT (internal issue 995).
* Clarify aspect mask usage for image memory barriers of multi-plane
images in slink:VkImageSubresourceRange, slink:VkImageMemoryBarrier, and
the <<textures-layout-validation, Layout Validation>> section (internal
issue 996).
Other Issues:
* Fixed typo in flink:VkRenderPassSampleLocationsBeginInfoEXT (renamed
field pname:pSubpassSampleLocations to
pname:pPostSubpassSampleLocations).
* Add missing buffer usage requirements for indirect draws in
flink:vkCmdDrawIndirect, flink:vkCmdDrawIndirectCountAMD,
flink:vkCmdDrawIndexedIndirect, and
flink:vlCmdDrawIndexedIndirectCountAMD.
* Modify Makefile to allow specification to build in git "`detached HEAD`"
state.
* Update valid usage ID generation script to allow recursively operating
on all `.txt` files in a specified directory, and move the `startVUID`
tracking information into a separate python file that is automatically
updated by the script.
New Extensions:
* Add +vk.xml+ entries for pending `VK_ANDROID_native_buffer` extension
(note, this extension is not yet enabled).
* `VK_AMD_shader_image_load_store_lod`
