Jon Leech 1d67e47f14 Change log for June 4, 2017 Vulkan 1.0.51 spec update:
* Bump API patch number and header version number to 51 for this update.

Github Issues:

  * Add Valid Usage statement to flink:vkCmdResolveImage to require that
    source and destination image formats match (public issue 492).
  * Specify that a code:char* parameter must: be a valid null-terminated
    string in the <<fundamentals-implicit-validity, implicit valid usage>>
    section (public issue 494).
  * Removed unnecessary VU for slink:VkPhysicalDeviceFeatures which is
    covered by ename:VK_ERROR_FEATURE_NOT_PRESENT already (public issue
    496).
  * Clarify valid usage of pname:pQueueFamilyIndices in
    slink:VkBufferCreateInfo, slink:VkImageCreateInfo, and
    slink:VkSwapchainCreateInfoKHR (public issue 501).
  * Document that dependencies of enabled extensions must also be enabled in
    the <<extended-functionality-extensions-dependencies, Extension
    Dependencies>> section (public issue 507).

Internal Issues:

  * Change slink:VkMappedMemoryRange valid usage to allow pname:offset +
    pname:size == size of the allocation. Also, if ename:VK_WHOLE_SIZE is
    used, require the end of the mapping to be aligned to a multiple of
    pname:nonCoherentAtomSize (internal issue 611).
  * Add issue to `VK_KHR_win32_surface` about reusing window objects from a
    different graphics API or Vulkan ICD (internal issue 639).
  * Require locations on user in/out in `GL_KHR_vulkan_glsl` (internal issue
    783).
  * Added version info to the json validation output, and updated the schema
    to match (internal issue 838).
  * Restructure enumerated type descriptions separately from the command or
    structure they are used in, allowing better reference page generation
    (internal issue 841).
  * Re-sort extension appendices to be in alphabetical order within each
    author ID section.
  * Fix enum naming and clarify behavior for
    `VK_NVX_device_generated_commands` extension.

Vulkan Asciidoc Configuration Files

Macros

The macros in vulkan-macros.rb and vulkan-macros/extension.rb are described in the "Vulkan Documentation and Extensions: Procedures and Conventions" document (see the styleguide).

Support for Math

Asciidoctor is customized to insert KaTeX <script> tags from math.js for HTML5, and properly pass through math which has \begin{}\/end{} delimiters instead of $$[].

For PDF builds, asciidoctor-mathematical is used to generate

math-docbook.conf is heavily conditionalized depending on whether the final output format (which should be described in the a2x-format variable) is pdf or not, since Docbook passes through math differently to dblatex vs. the XHTML stylesheets. This could be simplified now that we're only using Docbook for PDFs.
