* Bump API patch number and header version number to 26 for this update. Github Issues: * Bring sample code in the +VK_KHR_surface+ and +VK_KHR_swapchain+ extension summary appendices up to date, and note they will be replaced with pointers to the LunarG SDK examples in the future (public issue 279). * Add a new <<fundamentals-commandsyntax-results-lifetime,Lifetime of Retrieved Results>> section specifying that ftext:vkGet* and ftext:VkEnumerate* results are invariant unless otherwise specified, and specify behavior for individual commands which are not invariant (public issue 280). * Remove conflicting definition of slink:VkDisplayPlaneCapabilitiesKHR::pname:maxSrcPosition and clean up language of the remaining definition (public issue 351). * Fix many minor spelling errors and add rules to the style guide to prevent recurrences (public issue 352). Internal Issues: * Remove redundant descriptions of the etext:VK_USE_PLATFORM_* macros from the <<wsi,Window System Integration>> chapter in favor of the description in the <<boilerplate-wsi-header,Window System-Specific Header Control>> appendix (internal issue 6). * Replace misleading 'can: be destroyed when not X' with more correct 'must: not be destroyed while X' in the <<fundamentals-objectmodel-lifetime,Object Lifetime>> section. Disallow destroying a pipeline layout while a command buffer using it is recording (internal issue 241). * Clarify that ename:VK_IMAGE_USAGE_TRANSIENT_ATTACHMENT_BIT is valid for all images used as attachments in elink:VkImageUsageFlagBits and the slink:VkImageLayout validity language (internal issue 320). * Note that <<extended-functionality-layers,Layers>> may wrap object handles, but that this is a generally discouraged. A link to additional information in the documentation for layer authors is provided (issue 398) * Replace the mustnot: and shouldnot: macros with equivalent must: not and should: not to get rid of non-English words while still highlighting normative language (internal issue 407). * Disallow creating multisampled images with ename:VK_IMAGE_CREATE_CUBE_COMPATIBLE_BIT in the slink:VkImageLayout validity language and the <<features-supported-sample-counts,Supported Sample Counts>> section (internal issue 445). * Fix typo so that flink:vkCmdDrawIndexedIndirect is defined in terms of flink:vkCmdDrawIndexed rather than flink:vkCmdDrawIndirect (internal issue 446). * Reorganize the per-extension information sections to all be in the <<extensions,Layers & Extensions>> appendix. Also fix a typo in +VK_IMG_filter_cubic+ which incorrectly identified it as a +KHR+ extension (internal issue 461). Other Issues: * Use asciidoc markup instead of latexmath to simplify diagrams in the <<features-formats-non-packed,byte mapping tables>> for color formats. * Fix a markup problem with the wildcarded enumerant names in a NOTE in the <<textures-texel-replacement,Texel Replacement>> section. * Fix missing attributes in the XML interface for elink:VkExternalMemoryHandleTypeFlagBitsNV and elink:VkExternalMemoryFeatureFlagBitsNV (KhronosGroup/Vulkan-Hpp issue #25) * Cleanup reference page builds so only core pages are built for releases.

This extension allows GLSL shaders written to the +GL_KHR_vulkan_glsl+
|
|
extension specification to be used instead of SPIR-V. The implementation
|
|
will automatically detect whether the shader is SPIR-V or GLSL and
|
|
compile it appropriatly.
