## Description

This extension adds some more dynamic state to support applications that need to reduce the number of pipeline state objects they compile and bind.

## New Commands

- vkCmdSetDepthBiasEnableEXT

- vkCmdSetLogicOpEXT

- vkCmdSetPatchControlPointsEXT

- vkCmdSetPrimitiveRestartEnableEXT

- vkCmdSetRasterizerDiscardEnableEXT

## New Structures

- Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:

  - VkPhysicalDeviceExtendedDynamicState2FeaturesEXT

## New Enum Constants

- `VK_EXT_EXTENDED_DYNAMIC_STATE_2_EXTENSION_NAME`

- `VK_EXT_EXTENDED_DYNAMIC_STATE_2_SPEC_VERSION`

- Extending VkDynamicState:

  - `VK_DYNAMIC_STATE_DEPTH_BIAS_ENABLE_EXT`

  - `VK_DYNAMIC_STATE_LOGIC_OP_EXT`

  - `VK_DYNAMIC_STATE_PATCH_CONTROL_POINTS_EXT`

  - `VK_DYNAMIC_STATE_PRIMITIVE_RESTART_ENABLE_EXT`

  - `VK_DYNAMIC_STATE_RASTERIZER_DISCARD_ENABLE_EXT`

- Extending VkStructureType:

  - `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_EXTENDED_DYNAMIC_STATE_2_FEATURES_EXT`

## Promotion to Vulkan 1.3

The dynamic state enumerants `VK_DYNAMIC_STATE_DEPTH_BIAS_ENABLE_EXT`, `VK_DYNAMIC_STATE_PRIMITIVE_RESTART_ENABLE_EXT`, and `VK_DYNAMIC_STATE_RASTERIZER_DISCARD_ENABLE_EXT`; and the corresponding commands in this extension are included in core Vulkan 1.3, with the EXT suffix omitted. The enumerants and commands for dynamic logic operation and patch control points are not promoted, nor is the feature structure. Extension interfaces that were promoted remain available as aliases of the core functionality.
