class ImageSourceSkia : public ImageSource {
public:
// FIXME: This class is a hack to support Chromium's ICO decoder
// Currently our ICO decoder decodes all data during setData() instead of
// being lazy. In addition, it only decodes one frame (closest to the size
// passed to the decoder during createDecoder, called from setData) and
// discards all other data in the file.
//
// To fix this will require fixing the ICO decoder to be lazy, or to decode
// all frames. Apple's decoders (ImageIO) decode all frames, and return
// them all sorted in decreasing size. WebCore always draws the first frame.
//
// This is a special-purpose routine for the favicon decoder, which is used
// to specify a particular icon size for the ICOImageDecoder to prefer
// decoding. Note that not all favicons are ICOs, so this won't
// necessarily do anything differently than ImageSource::setData().
//
// Passing an empty IntSize for |preferredIconSize| here is exactly
// equivalent to just calling ImageSource::setData(). See also comments in
// ICOImageDecoder.cpp.
void setData(SharedBuffer* data,
bool allDataReceived,
const IntSize& preferredIconSize);
