+//
+// Function for loading a WIC image and creating a Direct3D runtime texture for it
+// (auto-generating mipmaps if possible)
+//
+// 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.
