## Description

This extension adds more expressive alignment requirements for uniform and storage texel buffers. Some implementations have single texel alignment requirements that cannot be expressed via VkPhysicalDeviceLimits::`minTexelBufferOffsetAlignment`.

## New Structures

- Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:

  - VkPhysicalDeviceTexelBufferAlignmentFeaturesEXT

- Extending VkPhysicalDeviceProperties2:

  - VkPhysicalDeviceTexelBufferAlignmentPropertiesEXT

## New Enum Constants

- `VK_EXT_TEXEL_BUFFER_ALIGNMENT_EXTENSION_NAME`

- `VK_EXT_TEXEL_BUFFER_ALIGNMENT_SPEC_VERSION`

- Extending VkStructureType:

  - `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_TEXEL_BUFFER_ALIGNMENT_FEATURES_EXT`

  - `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_TEXEL_BUFFER_ALIGNMENT_PROPERTIES_EXT`

## Promotion to Vulkan 1.3

Functionality in this extension is included in core Vulkan 1.3, with the EXT suffix omitted. However, only the properties structure is promoted. The feature structure is not promoted. The original type name is still available as an alias of the core functionality.

## Version History

- Revision 1, 2019-06-06 (Jeff Bolz)

  - Initial draft
