## Description

`VK_EXT_filter_cubic` extends `VK_IMG_filter_cubic`.

It documents cubic filtering of other image view types. It adds new structures that can be added to the `pNext` chain of VkPhysicalDeviceImageFormatInfo2 and VkImageFormatProperties2 that can be used to determine which image types and which image view types support cubic filtering.

## New Structures

- Extending VkImageFormatProperties2:

  - VkFilterCubicImageViewImageFormatPropertiesEXT

- Extending VkPhysicalDeviceImageFormatInfo2:

  - VkPhysicalDeviceImageViewImageFormatInfoEXT

## New Enum Constants

- `VK_EXT_FILTER_CUBIC_EXTENSION_NAME`

- `VK_EXT_FILTER_CUBIC_SPEC_VERSION`

- Extending VkFilter:

  - VK_FILTER_CUBIC_EXT

- Extending VkFormatFeatureFlagBits:

  - VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_CUBIC_BIT_EXT

- Extending VkStructureType:

  - VK_STRUCTURE_TYPE_FILTER_CUBIC_IMAGE_VIEW_IMAGE_FORMAT_PROPERTIES_EXT

  - VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_IMAGE_VIEW_IMAGE_FORMAT_INFO_EXT
