The +VK_KHR_relaxed_block_layout+ extension allows implementations to
indicate they can support more variation in block code:Offset decorations.
For example, placing a vector of three floats at an offset of 16*N + 4.

See <<interfaces-resources-layout,Offset and Stride Assignment>> for
details.

=== Version History
  * Revision 1, 2017-03-26 (JohnK)
Change log for August 1, 2017 Vulkan 1.0.57 spec update: * Bump API patch number and header version number to 57 for this update. Github Issues: * Fix error in description of ename:VK_FORMAT_ETC2_R8G8B8A8_SRGB_BLOCK block size (public issue 342). * Update documentation of ename:VK_PIPELINE_CREATE_ALLOW_DERIVATIVES_BIT to explicitly mention both graphics and compute pipelines (public issue 525). Internal Issues: * Document that slink:VkPhysicalDeviceLimits::pname:framebufferColorSampleCounts does not cover integer formats (internal issue 550). * Add a note under slink:VkImageViewCreateInfo describing how values meant for one format can be sanitized when used via another format (internal issue 927). * Add valid usage statements to ftext:vkCmd* documenting that image subresources used as attachments must not be accessed as non-attachments in a render pass (internal issue 929). * Remove obsolete 'validextensionstructs' attribute from +vk.xml+, the XML schema, and the schema documentation (internal issue 946). New Extensions: * `VK_AMD_mixed_attachment_samples` * `VK_EXT_post_depth_coverage` * `VK_KHR_relaxed_block_layout` * `VK_NV_depth_range_unrestricted` 2017-08-01 00:22:11 +00:00			`// Copyright (c) 2016-2017 Khronos Group.
