Overview
This sample demonstrates one of the functionalities of VK_EXT_extended_dynamic_state3 related to rasterization samples.
The extension can be used to dynamically change sampling without need to swap pipelines.
Enabling the extension
To be able to use this extension in Vulkan API:
VK_EXT_extended_dynamic_state3 depends on VK_KHR_get_physical_device_properties2, which is promoted to Vulkan 1.1. That is, to use this extension, VK_EXT_extended_dynamic_state3 and either VK_KHR_get_physical_device_properties2 or Vulkan 1.1 are required.
Additionally this sample uses VK_KHR_dynamic_rendering which required Vulkan 1.2.
Using the extension
To use the extension:
1) VK_DYNAMIC_STATE_RASTERIZATION_SAMPLES_EXT must be added to VkPipelineDynamicStateCreateInfo.
2) Method void vkCmdSetRasterizationSamplesEXT(VkCommandBuffer commandBuffer, VkSampleCountFlagBits rasterizationSamples) should be called with the active command buffer.
