Jon Leech 1ca0ea1ef0 Change log for July 22, 2016 Vulkan 1.0.22 spec update:
* Bump API patch number and header version number to 22 for this update.

Github Issues:

  * Translate the subpass self-dependency language into concrete
    validity statements, and added a validity statement about the
    restrictions on layout parameters (public issue 267).
  * Add validity requirement that
    slink:VkAttachmentDescription::pname:finalLayout and
    slink:VkAttachmentReference::pname:layout must not be
    ename:VK_IMAGE_LAYOUT_UNDEFINED or
    ename:VK_IMAGE_LAYOUT_PREINITIALIZED (public issue 268).
  * Clarify that slink:VkSubpassDescription::pname:pResolveAttachments
    layouts are used. Make language consistent with other attachment
    arrays (public issue 270).
  * Changed 64-bit definition for
    dname:VK_DEFINE_NON_DISPATCHABLE_HANDLE to work for x32 platform in
    +vk.xml+ and the resulting +vulkan.h+ (public issue 282).
  * Add missing error return code for
    flink:vkEnumerateInstanceExtensionProperties and
    flink:vkEnumerateDeviceExtensionProperties (public issue 285)
  * Fix several cases of stext::VkStructName.memberName markup to
    stext::VkStructName::pname:memberName, to match other usage in the
    spec, and describe this markup in the style guide (public issue
    286).
  * Modified validity language generation script to avoid redundant
    common ancestor language if covered by generic parent language, and
    used `Both' instead of `Each' when appropriate (public issue 288).

Internal Issues:

  * Add language about behavior of flink:vkAllocateDescriptorSets when
    allocation fails due to fragmentation, a new error
    ename:VK_ERROR_FRAGMENTED_POOL, and a Note explaining the situation
    (internal issue 309).
  * For the features of code:PointSize, code:ClipDistance, and
    code:CullDistance, the SPIR-V capability is required to be declared
    on use (read or write) rather than on decoration (internal issue
    359).
  * Have desktop versions of GLSL respect precision qualification
    (code:mediump and code:lowp) when compiling for Vulkan. These will
    get translated to SPIR-V's code:RelaxedPrecision decoration as they
    do with OpenGL ES versions of GLSL (ESSL). The default precision of
    all types is code:highp when using a desktop version (internal issue
    360).
  * Add validity statement for slink:VkImageCreateInfo specifying that
    multisampled images must be two-dimensional, optimally tiled, and
    with a single mipmap level (internal issue 369).
  * Add validity statements to slink:VkImageViewCreateInfo disallowing
    creation of images or image views with no supported features. Made
    some slink:VkImageViewCreateInfo validity statements more precise
    and consistent. Added a Note to the <<features,features>> chapter
    about formats with no features (internal issue 371).
  * Remove +manpages+ from default build targets. Nroff outputs
    containing imbedded latexmath will not render properly. Fixing this
    is a lot of work for limited use cases (internal issue 401).

Other Commits:

  * Fix flink:vkRenderPassBeginInfo::pname:clearValueCount validity
    statement to be based on attachment indices rather than the number
    of cleared attachments
    (Vulkan-LoaderAndValidationLayers/issues/601).
  * Convert registry documentation from LaTeX to asciidoc source and
    rename from +src/spec/readme.tex+ to +src/spec/registry.txt+.
  * Fix lack of Oxford commas in validity language.
  * Lots of cleanup of generator scripts and Makefiles to move extension
    list for generator into the script arguments instead of the body of
    genvk.py, and express better dependencies between XML, scripts, and
    generated files.

VkSparseImageMemoryRequirements - Structure specifying sparse image memory requirements
C Specification
---------------
// refBegin VkSparseImageMemoryRequirements - Structure specifying sparse image memory requirements
The sname:VkSparseImageMemoryRequirements structure is defined as:
include::../api/structs/VkSparseImageMemoryRequirements.txt[]
Members
-------
* pname:formatProperties.aspectMask is the set of aspects of the image
that this sparse memory requirement applies to. This will usually have a
single aspect specified. However, depth/stencil images may: have depth
and stencil data interleaved in the same sparse block, in which case
both ename:VK_IMAGE_ASPECT_DEPTH_BIT and
ename:VK_IMAGE_ASPECT_STENCIL_BIT would be present.
* pname:formatProperties.imageGranularity describes the dimensions of a
single bindable sparse image block in pixel units. For aspect
ename:VK_IMAGE_ASPECT_METADATA_BIT, all dimensions will be zero
pixels. All metadata is located in the mip tail region.
* pname:formatProperties.flags is a bitmask of
elink:VkSparseImageFormatFlagBits:
** If ename:VK_SPARSE_IMAGE_FORMAT_SINGLE_MIPTAIL_BIT is set the image
uses a single mip tail region for all array layers.
** If ename:VK_SPARSE_IMAGE_FORMAT_ALIGNED_MIP_SIZE_BIT is set the
dimensions of mip levels must: be integer multiples of the corresponding
dimensions of the sparse image block for levels not located in the mip
tail.
** If ename:VK_SPARSE_IMAGE_FORMAT_NONSTANDARD_BLOCK_SIZE_BIT is set the
image uses non-standard sparse image block dimensions. The
pname:formatProperties.imageGranularity values do not match the
standard sparse image block dimension corresponding to the image's
pixel format.
* pname:imageMipTailFirstLod is the first mip level at which image
subresources are included in the mip tail region.
* pname:imageMipTailSize is the memory size (in bytes) of the mip tail
region. If pname:formatProperties.flags contains
ename:VK_SPARSE_IMAGE_FORMAT_SINGLE_MIPTAIL_BIT, this is the size of the
whole mip tail, otherwise this is the size of the mip tail of a single
array layer. This value is guaranteed to be a multiple of the sparse block
size in bytes.
* pname:imageMipTailOffset is the opaque memory offset used with
slink:VkSparseImageOpaqueMemoryBindInfo to bind the mip tail region(s).
* pname:imageMipTailStride is the offset stride between each array-layer's
mip tail, if pname:formatProperties.flags does not contain
ename:VK_SPARSE_IMAGE_FORMAT_SINGLE_MIPTAIL_BIT (otherwise the value is
undefined).
