// Function for loading a WIC image and creating a Direct3D runtime texture for it
//
// Note: Assumes application has already called CoInitializeEx
//
// Note these functions are useful for images created as simple 2D textures. For
// more complex resources, DDSTextureLoader is an excellent light-weight runtime loader.
// For a full-featured DDS file reader, writer, and texture processing pipeline see
// the 'Texconv' sample and the 'DirectXTex' library.
