 // LayoutImage is used to display any image type.

 // * normal images, e.g. <image>, <picture>.
 // * content images with "content: url(path/to/image.png)".
 // We store the type inside  m_isGeneratedContent.
 //
 // The class is image type agnostic as it only manipulates decoded images.
 // See LayoutImageResource that holds this image.
