Jon Leech df88ded281 Change log for September 5, 2017 Vulkan 1.0.60 spec update:
* Bump API patch number and header version number to 60 for this update.

Github Issues:

  * Document that <<queries-timestamps, Timestamp Queries>> can only be
    meaningfully compared when they are written from the same queue (public
    issue 216).
  * Document that the `<extension>` tag `type` attribute is required for
    non-disabled extensions (derived from, but does not close public issue
    354).
  * Clean up registry schema length attribute descriptions to be consistent
    and correct (public issue 555).

Internal Issues:

  * Replace as much of the hand-written extension appendix metadata as
    possible with asciidoc includes generated from corresponding attributes
    of +vk.xml+, and enhance the style guide to match. This avoids
    inconsistencies between +vk.xml+ and the appendices, and produces a more
    uniform style (internal issue 137).
  * Remove the generated extDependency.{py,sh} files from the tree and
    create them dynamically on demand instead, reducing merge conflicts
    (internal issue 713).
  * Add a prototype tool for generating in-place difference markup for
    sections guarded by asciidoc conditionals, and new syntax for open
    blocks to support it (internal issue 833).
  * Remove unnecessary restriction of etext:*SYNC_FD_BIT_KHR external handle
    types to the same physical device in the
    slink:VkPhysicalDeviceIDPropertiesKHR,
    flink:VkImportMemoryWin32HandleInfoKHR,
    slink:VkImportFenceWin32HandleInfoKHR, slink:VkImportFenceFdInfoKHR,
    slink:VkImportSemaphoreWin32HandleInfoKHR,
    slink:VkImportSemaphoreFdInfoKHR
    <<external-memory-handle-types-compatibility, External memory handle
    types compatibility>>, <<external-semaphore-handle-types-compatibility,
    External semaphore handle types compatibility>>, and
    <<external-fence-handle-types-compatibility, External fence handle types
    compatibility>> sections (internal issue 956).

Other Issues:

  * Remove dependency of +VK_KHX_device_group+ on +VK_KHR_swapchain+ (there
    is an interaction, but not a strict dependency), and add a new
    `extension` attribute to the `<require` XML tag to allow classifying a
    subset of interfaces of an extension as requiring another extension.
    Update the registry schema and documentation accordingly.

New Extensions:

  * `VK_AMD_shader_fragment_mask` (and related `GL_AMD_shader_fragment_mask`
    GLSL extension)
  * `VK_EXT_sample_locations`
  * `VK_EXT_validation_cache`
