## Description

This extension provides new queries for device display properties and capabilities that can be easily extended by other extensions, without introducing any further queries. This extension can be considered the `VK_KHR_display` equivalent of the `VK_KHR_get_physical_device_properties2` extension.

## New Commands

- vkGetDisplayModeProperties2KHR

- vkGetDisplayPlaneCapabilities2KHR

- vkGetPhysicalDeviceDisplayPlaneProperties2KHR

- vkGetPhysicalDeviceDisplayProperties2KHR

## New Structures

- VkDisplayModeProperties2KHR

- VkDisplayPlaneCapabilities2KHR

- VkDisplayPlaneInfo2KHR

- VkDisplayPlaneProperties2KHR

- VkDisplayProperties2KHR

## New Enum Constants

- `VK_KHR_GET_DISPLAY_PROPERTIES_2_EXTENSION_NAME`

- `VK_KHR_GET_DISPLAY_PROPERTIES_2_SPEC_VERSION`

- Extending VkStructureType:

  - `VK_STRUCTURE_TYPE_DISPLAY_MODE_PROPERTIES_2_KHR`

  - `VK_STRUCTURE_TYPE_DISPLAY_PLANE_CAPABILITIES_2_KHR`

  - `VK_STRUCTURE_TYPE_DISPLAY_PLANE_INFO_2_KHR`

  - `VK_STRUCTURE_TYPE_DISPLAY_PLANE_PROPERTIES_2_KHR`

  - `VK_STRUCTURE_TYPE_DISPLAY_PROPERTIES_2_KHR`

## Issues

1) What should this extension be named?

RESOLVED: `VK_KHR_get_display_properties2`. Other alternatives:

- `VK_KHR_display2`

- One extension, combined with `VK_KHR_surface_capabilites2`.

2) Should extensible input structs be added for these new functions:

RESOLVED:

- vkGetPhysicalDeviceDisplayProperties2KHR: No. The only current input is a VkPhysicalDevice. Other inputs would not make sense.

- vkGetPhysicalDeviceDisplayPlaneProperties2KHR: No. The only current input is a VkPhysicalDevice. Other inputs would not make sense.

- vkGetDisplayModeProperties2KHR: No. The only current inputs are a VkPhysicalDevice and a VkDisplayModeKHR. Other inputs would not make sense.

3) Should additional display query functions be extended?

RESOLVED:

- vkGetDisplayPlaneSupportedDisplaysKHR: No. Extensions should instead extend vkGetDisplayPlaneCapabilitiesKHR().
