VkTextureLODGatherFormatPropertiesAMD

To determine if texture gather functions that take explicit LOD and/or bias argument values can be used with a given image format, add a VkTextureLODGatherFormatPropertiesAMD structure to the pNext chain of the VkImageFormatProperties2 structure in a call to vkGetPhysicalDeviceImageFormatProperties2.

The VkTextureLODGatherFormatPropertiesAMD structure is defined as:

typedef struct VkTextureLODGatherFormatPropertiesAMD {
    VkStructureType sType;
    void* pNext;
    VkBool32 supportsTextureGatherLODBiasAMD;
} VkTextureLODGatherFormatPropertiesAMD;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• supportsTextureGatherLODBiasAMD tells if the image format can be used with texture gather bias/LOD functions, as introduced by the VK_AMD_texture_gather_bias_lod extension. This field is set by the implementation. An application-specified value is ignored.
