## Description

This extension expands support for using `VK_IMAGE_TILING_LINEAR` images as color attachments when all the color attachments in the render pass instance have `VK_IMAGE_TILING_LINEAR` tiling. This extension adds a new flag bit `VK_FORMAT_FEATURE_2_LINEAR_COLOR_ATTACHMENT_BIT_NV` that extends the existing VkFormatFeatureFlagBits2KHR bits. This flag can be set for renderable color formats in the VkFormatProperties3KHR::`linearTilingFeatures` format properties structure member. Formats with the `VK_FORMAT_FEATURE_2_LINEAR_COLOR_ATTACHMENT_BIT_NV` flag may be used as color attachments as long as all the color attachments in the render pass instance have `VK_IMAGE_TILING_LINEAR` tiling, and the formats their images views are created with have VkFormatProperties3KHR::`linearTilingFeatures` which include `VK_FORMAT_FEATURE_2_LINEAR_COLOR_ATTACHMENT_BIT_NV`. This extension supports both dynamic rendering and traditional render passes.

## New Structures

- Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:

  - VkPhysicalDeviceLinearColorAttachmentFeaturesNV

## New Enum Constants

- `VK_NV_LINEAR_COLOR_ATTACHMENT_EXTENSION_NAME`

- `VK_NV_LINEAR_COLOR_ATTACHMENT_SPEC_VERSION`

- Extending VkStructureType:

  - `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_LINEAR_COLOR_ATTACHMENT_FEATURES_NV`

If VK_KHR_format_feature_flags2 or Vulkan Version 1.3 is supported:

- Extending VkFormatFeatureFlagBits2:

  - `VK_FORMAT_FEATURE_2_LINEAR_COLOR_ATTACHMENT_BIT_NV`
