/**
* This extension adds two related features.
*
* Firstly, support for the following SPIR-V extension in Vulkan is added:
*
*
* - SPV_AMD_texture_gather_bias_lod
*
*
* Secondly, the extension allows the application to query, which formats can be used together with the new function prototypes introduced by the SPIR-V extension.
*
* Examples
*
*
* struct VkTextureLODGatherFormatPropertiesAMD
* {
* VkStructureType sType;
* const void* pNext;
* VkBool32 supportsTextureGatherLODBiasAMD;
* };
*
* // ----------------------------------------------------------------------------------------
* // How to detect if an image format can be used with the new function prototypes.
* VkPhysicalDeviceImageFormatInfo2KHR formatInfo;
* VkImageFormatProperties2KHR formatProps;
* VkTextureLODGatherFormatPropertiesAMD textureLODGatherSupport;
*
* textureLODGatherSupport.sType = VK_STRUCTURE_TYPE_TEXTURE_LOD_GATHER_FORMAT_PROPERTIES_AMD;
* textureLODGatherSupport.pNext = nullptr;
*
* formatInfo.sType = VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_IMAGE_FORMAT_INFO_2_KHR;
* formatInfo.pNext = nullptr;
* formatInfo.format = ...;
* formatInfo.type = ...;
* formatInfo.tiling = ...;
* formatInfo.usage = ...;
* formatInfo.flags = ...;
*
* formatProps.sType = VK_STRUCTURE_TYPE_IMAGE_FORMAT_PROPERTIES_2_KHR;
* formatProps.pNext = &textureLODGatherSupport;
*
* vkGetPhysicalDeviceImageFormatProperties2KHR(physical_device, &formatInfo, &formatProps);
*
* if (textureLODGatherSupport.supportsTextureGatherLODBiasAMD == VK_TRUE)
* {
* // physical device supports SPV_AMD_texture_gather_bias_lod for the specified
* // format configuration.
* }
* else
* {
* // physical device does not support SPV_AMD_texture_gather_bias_lod for the
* // specified format configuration.
* }
