## 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

Vulkan APIs in this extension are included in core Vulkan 1.3, with the EXT suffix omitted. However, only the properties structure is promoted. The feature structure is not promoted and `texelBufferAlignment` is enabled if using a Vulkan 1.3 instance. External interactions defined by this extension, such as SPIR-V token names, retain their original names. The original Vulkan API name is still available as an alias of the core functionality.
