This function is currently does nothing. For CG ports, it scales a rect by the ratio backingStoreSize / internalSize which is always 1. The constructor ImageBuffer::ImageBuffer() sets m_size and m_data.backingStoreSize to the same value always.

    m_size = IntSize(scaledWidth, scaledHeight);
    m_data.backingStoreSize = m_size;

For other ports ImageBuffer::sizeForDestinationSize() returns the passed rectangle.
