-// a PNG image contained in an SkBitmap object. The following code snippet
-// shows an example usage of IconUtil::CreateHICONFromSkBitmap():
-//
-//   SkBitmap bitmap;
-//
-//   // Fill |bitmap| with valid data
-//   bitmap.setConfig(...);
-//   bitmap.allocPixels();
-//
-//   ...
-//
-//   // Convert the bitmap into a Windows HICON
-//   HICON icon = IconUtil::CreateHICONFromSkBitmap(bitmap);
-//   if (icon == NULL) {
-//     // Handle error
-//     ...
-//   }
-//
-//   // Use the icon with a WM_SETICON message
-//   ::SendMessage(hwnd, WM_SETICON, static_cast<WPARAM>(ICON_BIG),
-//                 reinterpret_cast<LPARAM>(icon));
