Jon Leech 56e0289318 Change log for January 05, 2019 Vulkan 1.1.97 spec update:
* Update release number to 97.

Public Issues:

  * Add a special case to the <<renderpass-compatibility, Render Pass
    Compatibility>> rules allowing single-subpass renderpasses to be
    compatible even if they have different resolve attachment references
    (public issue 835).
  * Fix the miss shader binding table record address rule in the
    <<shader-binding-table-indexing-rules, Miss Shaders>> section to index
    by code:missIndex, not code:sbtOffset (public issue 875).

Internal Issues:

  * Add a missing anchor to the elink:VkSamplerCreateFlagBits language
    (internal issue 1483).
  * Add missing implicit valid usage include for slink:VkHdrMetadataEXT and
    corresponding `noautovalidity` attributes in `vk.xml` for the
    externally-defined metadata properties (internal issue 1514).
  * Remove restrictions on the `mask` parameter of SPIR-V's
    code:OpGroupNonUniformXor in the <<spirvenv-module-validation,
    Validation Rules within a Module>> appendix (internal merge request
    2971).
  * Restore `noautovalidity` attribute for
    slink:VkPipelineViewportWScalingStateCreateInfoNV::pname:pViewportWScalings
    in `vk.xml` (internal merge request 2975).
  * Update copyright dates on Khronos-copyrighted files to 2019 (internal
    merge request 2980).

New Extensions:

  * `VK_KHR_depth_stencil_resolve`
  * `VK_EXT_buffer_device_address`
  * `VK_EXT_memory_budget`
  * `VK_EXT_memory_priority`
  * `VK_EXT_validation_features`

The `VK_KHR_8bit_storage` extension allows use of 8-bit types in uniform and
storage buffers, and push constant blocks.
This extension introduces several new optional features which map to SPIR-V
capabilities and allow access to 8-bit data in code:Block-decorated objects
in the code:Uniform and the code:StorageBuffer storage classes, and objects
in the code:PushConstant storage class.
The code:StorageBuffer8BitAccess capability must: be supported by all
implementations of this extension.
The other capabilities are optional.
