Jon Leech b9e9296cd8 Change log for June 24, 2017 Vulkan 1.0.53 spec update:
* Bump API patch number and header version number to 53 for this update.

Github Issues:

Internal Issues:

  * Clarify mappings of coordinates for mutable, compatible image views in
    slink:VkImageViewCreateInfo (internal issue 815).
  * Make ename:VK_BIND_SFR_BIT require a logical device with multiple
    physical devices, so that standard sparse image block dimensions are
    only required on systems that support multi-GPU (internal issue 835).
  * Convert all files from use of // refBegin .. // refEnd comments to
    delimit ref pages, to use of open blocks, and update style guide
    accordingly (internal issue 839).
  * Add valid usage for slink:VkWriteDescriptorSet when performing updates
    to a ename:VK_STORAGE_IMAGE descriptor with layout
    ename:VK_IMAGE_LAYOUT_GENERAL.
  * Add a hack to the validity generator script to support an odd
    interaction between flink:vkCmdFillBuffer and an extension (internal
    issue 853).
  * Remove redundant text describing slink:VkBufferCreateInfo::pname:usage,
    which was already covered by implicit valid usage (internal issue 854).
  * Update implicit validity generator script to properly handle the
    pname:sType and pname:pNext members of "returnedonly" structures
    (internal issue 874).
  * Note that slink:VkApplicationInfo::pname:pApplicationName &
    slink:VkApplicationInfo::pname:pEngineName are optional, and add missing
    implicit valid usage statements for flink:vkDestroyInstance.
  * Added missing valid usage for flink:vkCmdWriteTimestamp to require a
    timestamp query pool.
  * Simplify and/or split "`non-atomic`" valid usage statements.

New Extensions:

  * `VK_AMD_gpu_shader_int16`
  * `VK_EXT_blend_operation_advanced`
  * `VK_EXT_sampler_filter_minmax`
  * `VK_NV_framebuffer_mixed_samples`

-----------------------------------------------------
Note: the 1.0.52 spec wasn't published on github, so the 1.0.53 release
combines both change sets.
-----------------------------------------------------

Change log for June 13, 2017 Vulkan 1.0.52 spec update:

  * Bump API patch number and header version number to 52 for this update.

Github Issues:

Internal Issues:

  * Clarify behavior when non-coherent memory has
    <<memory-device-unmap-does-not-flush, not been flushed before being
    unmapped>> (internal issue 819).
  * Fix description of code:WorkgroupSize builtin to note it decorates an
    object, not a variable (internal issue 836).
  * Fix asciidoc attributes so that trailing '{plus}' symbols in [eq] style
    equations are rendered properly (internal issue 845).
  * Add language to the "`Extension Handles, Objects, Enums, and Typedefs`"
    section of the Procedures and Conventions document stating that any new
    handle type requires a corresponding entry in the elink:VkObjectType
    enumerated type (internal issue 856).
  * Update style guide to use slink macro for Vulkan handle type names, and
    define narrow conditions under which to use the *name and *text macros
    instead of *link (internal issue 886).
  * Add a dependency of the <<VK_KHX_device_group,VK_KHX_device_group>>
    extension on VK_KHX_device_group_creation to +vk.xml+ and the extension
    appendix.
  * Change the copyright on Vulkan specification asciidoc *source* files to
    CC-BY 4.0, and update the proprietary Khronos copyright applied to the
    generated *output* formats (internal issue 327). This enables broader
    re-use and modification of the Vulkan specification sources, while not
    affecting the Reciprocal IP License between Vulkan Adopters and Working
    Group Members.

New Extensions:

  * `VK_NV_fill_rectangle`
  * `VK_NV_fragment_coverage_to_color`

This extension allows descriptors to be written into the command buffer,
with the implementation being responsible for managing their memory.
Push descriptors may enable easier porting from older APIs and in some cases
can be more efficient than writing descriptors into descriptor sets.
