## Description

This extension adds support for using vector types with more than four components in SPIR-V.

Long vector types are defined by the `SPV_EXT_long_vector` SPIR-V extension and can be used with the `GL_EXT_long_vector` GLSL extension.

## New Structures

- Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:

  - VkPhysicalDeviceShaderLongVectorFeaturesEXT

- Extending VkPhysicalDeviceProperties2:

  - VkPhysicalDeviceShaderLongVectorPropertiesEXT

## New Enum Constants

- `VK_EXT_SHADER_LONG_VECTOR_EXTENSION_NAME`

- `VK_EXT_SHADER_LONG_VECTOR_SPEC_VERSION`

- Extending VkStructureType:

  - VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_LONG_VECTOR_FEATURES_EXT

  - VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_LONG_VECTOR_PROPERTIES_EXT

## New SPIR-V Capabilities

- LongVectorEXT
