This extension adds support for an exclusive scissor test to Vulkan.
The exclusive scissor test behaves like the scissor test, except that the
exclusive scissor test fails for pixels inside the corresponding rectangle
and passes for pixels outside the rectangle.
If the same rectangle is used for both the scissor and exclusive scissor
tests, the exclusive scissor test will pass if and only if the scissor test
fails.
=== New Object Types

Change log for November 4, 2018 Vulkan 1.1.91 spec update: * Update release number to 91. Public Issues: * Update Ubuntu subsystem build instructions in `BUILD.adoc` (public pull request 624). * Delete the `VK_KHR_mir_surface` extension from the Specification and XML, due to EOL of the only driver known to have supported it, and near-EOL of Mir itself (public issue 814). * Fix options for some figures that were using old ones (public pull request 841). * Fix various accidentally repeated words (public pull request 843). * Use `time.process_time()`, introduced in Python 3.3, in the scripts instead of `time.clock()`, which will be removed in Python 3.8 (public pull request 844). Internal Issues: * Update valid usage statements for `VK_ANDROID_external_memory_android_hardware_buffer` in slink:VkMemoryAllocateInfo, slink:VkImportAndroidHardwareBufferInfoANDROID, and flink:vkGetAndroidHardwareBufferPropertiesANDROID to actually be verifiable (internal issue 1419). * Update valid usage statements for `VK_ANDROID_external_memory_android_hardware_buffer` in slink:VkMemoryAllocateInfo, slink:VkImageCreateInfo, and slink:VkImageViewCreateInfo to move valid usage statements in doubly-nested bullet points up one level, accomodating limitations of the valid usage extraction script that creates `validusage.json` (internal issue 1434). * Fix typo etext:VK_ACCESS_SHADING_RATE_IMAGE_BIT_NV to the correct ename:VK_ACCESS_SHADING_RATE_IMAGE_READ_BIT_NV. * Add missing etext:VK_STRUCTURE_TYPE_* tokens to appendices for extensions missing them. New Extensions: * `VK_AMD_memory_overallocation_behavior` * `VK_NV_ray_tracing`, replacing `VK_NVX_raytracing`

Change log for November 12, 2018 Vulkan 1.1.92 spec update: * Update release number to 92. Public Issues: * Move and modify valid usage statements dealing with pname:aspectMask in flink:vkCmdClearColorImage, flink:vkCmdClearDepthStencilImage, and slink:VkClearAttachment, so they are in places where all necessary information is available (public issue 529). * Fix math markup in <<textures-texel-anisotropic-filtering, Texel Anisotropic Filtering>> (public pull request 840). * Fix misspellings (public pull request 845). Internal Issues: * Add installation instructions and a Makefile "`chunked`" target for chunked HTML generation (internal issue 1352). * Fix pipeline mesh diagram style; also fix a minor bug in the classic pipeline diagram where vertex/index buffers wrongly fed into the vertex shader (internal issue 1436). * Make asciidoctor ERROR output raise an error, and don't suppress executed command output from CI make invocation (internal issue 1454). * Minor typo fixes and clarifications for `VK_NV_raytracing`. * Cleanup extension-specific properties ** Remove duplicated documentation for pname:maxDiscardRectangles, pname:pointClippingBehavior, and pname:maxVertexAttribDivisor (they shouldn't be documented with the other members of slink:VkPhysicalDeviceLimits at all). ** Remove duplicate anchor for pname:maxVertexAttribDivisor ** Consistently document stext:VkPhysicalDevice<Extension>PropertiesKHR *** Always document pname:sType/pname:pNext (was inconsistent before) *** Always mention chaining to slink:VkPhysicalDeviceProperties2 (and not as slink:VkPhysicalDeviceProperties2KHR) *** Always include Valid Usage statements last * Update Makefile 'checklinks' target and associated scripts, and fix markup problems identified by checkLinks.py, so that we can rely on the checklinks script as part of Gitlab CI.

=== Issues
1) For the scissor test, the viewport state must be created with a matching
number of scissor and viewport rectangles.
Should we have the same requirement for exclusive scissors?
*RESOLVED*: For exclusive scissors, we relax this requirement and allow an
exclusive scissor rectangle count that is either zero or equal to the number
of viewport rectangles.
If you pass in an exclusive scissor count of zero, the exclusive scissor
test is treated as disabled.
