Change log for April 29, 2016 Vulkan 1.0.12 spec update: 

* Bump API patch number and header version number to 12 for this
    update.

Github Issues:

  * Change valid usage statements intended to be "sub-points" to
    be actual sub-points (public issue 66).
  * Replace double negation in description of
    slink:VkRenderPassBeginInfo::pname:pClearValues (based on public
    merge 142).
  * Cleanup minor typos in spec, ref pages and XML, including those
    proposed in public pull requests 144, 150, 151, 167, 168, 181, and
    186.
  * Use *strict subset* in describing the partial order of memory
    property types for slink:VkMemoryType, and update the style guide
    accordingly (public issue 190).
  * Fix various "a image" -> "an image" typos (public issue 191).
  * Note in the <<fundamentals-validusage,Valid Usage>> and
    <<extensions-interactions,Extension Interactions>> sections that
    structures defined by extensions which may be passed in structure
    chains using the ptext:pNext member must: include initial
    ptext:sType and ptext:pNext members (public issue 192).

Internal Issues:

  * Remove duplicate language from the description of the pname:fence
    parameter to flink:vkQueueSubmit and improve validity language
    (internal issue 91).
  * Added documentation for "optional" attribute to XML readme.tex/pdf
    (internal issue 149).
  * Clarify the host-side data validity rules and behavior of
    flink:vkFlushMappedMemoryRanges and
    flink:vkInvalidateMappedMemoryRanges (internal issue 266).

Other Commits:

  * Added clarification to flink:vkCmdFillBuffer regarding the use of
    ename:VK_WHOLE_SIZE.
  * Fixed and documented implementation of "validextensionstructs"
    attribute. in XML processing scripts and readme.tex/pdf.
  * Add missing validity statements to flink:vkResetEvent and
    flink:vkCmdResetEvent.
  * Fix validity for the
    ename:VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_LINEAR_BIT flag.
    Correct all the draw/dispatch commands to mention optimally tiled
    images as well as linear tiled images, and say image VIEWS instead
    of images. Add validity statement to flink:vkCmdBlitImage
  * Replace the {apiname} macro with hardcoded "Vulkan", now that we've
    committed to that name.
  * Add the VK_AMD_rasterization_order extension to vk.xml.
