+// Function for saving 2D surface to a file (aka a 'screenshot'
+// when used on a Direct3D 9's GetFrontBufferData).
+//
+// Note these functions are useful as a light-weight runtime screen grabber. For
+// full-featured texture capture, DDS writer, and texture processing pipeline,
+// see the 'Texconv' sample and the 'DirectXTex' library.
