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.
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.
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.
