Change log for October 7, 2018 Vulkan 1.1.87 spec update: * Update release number to 87. Public Issues: * Merge flink:vkCmdPipelineBarrier self-dependency barrier VUs referring to the same subpass dependency (public pull request 756). * Describe default value of `"optional"` attribute in the registry schema document (public issue 769) * Fix links in <<VK_NVX_raytracing>> extension (public pull request 805). * Mark the <<VK_KHR_mir_surface>> extension obsolete (see public issue 814 - does not close this, however). * Fix missing endif in Image Creation block (public issue 817). Internal Issues: * Clarify that the compressed texture formats corresponding to <<features-features-textureCompressionETC2>>, <<features-features-textureCompressionASTC_LDR>>, and <<features-features-textureCompressionBC>> is not contingent on the feature bits, and may be supported even if the features are not enabled (internal issue 663). * Clarify that code:FragStencilRefEXT is output only in the <<interfaces-builtin-variables, Built-In Variables>> section (internal issue 1173). * Identify and correct many overly-aggressive uses of "`undefined`", and narrow them down, where straightforward to do so. Mark such resolved uses of "`undefined`" with the custom undefined: macro. Add a new <<writing-undefined, Describing Undefined Behavior>> section (internal issue 1267). * Don't require code:inline_uniform_block descriptors to be populated before use in the flink:vkAllocateDescriptorSets section (internal issue 1380). * Allow suppressing inline SVG images by controlling this with an attribute set in the Makefile, rather than the explicit [%inline] directive (internal issue 1391). * Mark 'Khronos' as a registered trademark in several places, now that it is one. * Fix typo in the <<VK_KHR_shader_atomic_int64>> appendix using the GLSL naming of the compare exchange op when referring to the SPIR-V op. * Specify in the flink:vkGetPhysicalDeviceQueueFamilyProperties section that all implementations must support at least one queue family, and that every queue family must contain at least one queue. * Make slink:VkPipelineDynamicStateCreateInfo::pname:dynamicStateCount, slink:VkSampleLocationsInfoEXT::pname:sampleLocationsPerPixel, and slink:VkSampleLocationsInfoEXT::pname:sampleLocationsCount optional, to fix bogus implicit valid usage checks that were causing failures in the conformance tests. * Fix vendor tag in reserved extension 237 constants. Does not affect anything since it's just a placeholder, but this should avoid further comments. * Minor markup fixes in some extension appendices. New Extensions: * `<<VK_FUCHSIA_imagepipe_surface>>`

To create a sname:VkSurfaceKHR object for a Fuchsia ImagePipe, call:
include::../../api/protos/vkCreateImagePipeSurfaceFUCHSIA.txt[]
* pname:instance is the instance to associate with the surface.
* pname:pCreateInfo is a pointer to an instance of the
slink:VkImagePipeSurfaceCreateInfoFUCHSIA structure containing
parameters affecting the creation of the surface object.
* pname:pAllocator is the allocator used for host memory allocated for the
surface object when there is no more specific allocator available (see
<<memory-allocation,Memory Allocation>>).
* pname:pSurface points to a slink:VkSurfaceKHR handle in which the
created surface object is returned.

[open,refpage='VkImagePipeSurfaceCreateInfoFUCHSIA',desc='Structure specifying parameters of a newly created ImagePipe surface object',type='structs']

The sname:VkImagePipeSurfaceCreateInfoFUCHSIA structure is defined as:
include::../../api/structs/VkImagePipeSurfaceCreateInfoFUCHSIA.txt[]
* pname:sType is the type of this structure.
* pname:pNext is `NULL` or a pointer to an extension-specific structure.
* pname:flags is reserved for future use.
* pname:imagePipeHandle is a code:zx_handle_t referring to the ImagePipe
to associate with the surface.
.Valid Usage
****
* [[VUID-VkImagePipeSurfaceCreateInfoFUCHSIA-imagePipeHandle-00000]]
pname:imagePipeHandle must: be a valid code:zx_handle_t

On Fuchsia, the surface pname:currentExtent is the special value
[eq]#(0xFFFFFFFF, 0xFFFFFFFF)#, indicating that the surface size will be
determined by the extent of a swapchain targeting the surface.
