// Functions for loading a DDS texture using the XBOX extended header and creating a
// Direct3D11.X runtime resource for it via the CreatePlacement APIs
//
// Note these functions will not load standard DDS files. Use the DDSTextureLoader
// module in the DirectXTex package or as part of the DirectXTK library to load
// these files which use standard Direct3D resource creation APIs.
