## Description

This extension allows applications to clamp the minimum LOD value during Image Level(s) Selection, Texel Gathering and Integer Texel Coordinate Operations with a given VkImageView by VkImageViewMinLodCreateInfoEXT::`minLod`.

This extension may be useful to restrict a VkImageView to only mips which have been uploaded, and the use of fractional `minLod` can be useful for smoothly introducing new mip levels when using linear mipmap filtering.

## New Structures

- Extending VkImageViewCreateInfo:

  - VkImageViewMinLodCreateInfoEXT

- Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:

  - VkPhysicalDeviceImageViewMinLodFeaturesEXT

## New Enum Constants

- `VK_EXT_IMAGE_VIEW_MIN_LOD_EXTENSION_NAME`

- `VK_EXT_IMAGE_VIEW_MIN_LOD_SPEC_VERSION`

- Extending VkStructureType:

  - `VK_STRUCTURE_TYPE_IMAGE_VIEW_MIN_LOD_CREATE_INFO_EXT`

  - `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_IMAGE_VIEW_MIN_LOD_FEATURES_EXT`
