37 QTextImageHandler would attempt to resolve relative paths, and load the
38 image itself if the document returns an invalid image from loadResource().
39 We replace it with this version instead, because Qt Quick's text resources
40 are resolved against the Text item's context, and because we override
41 intrinsicSize(). drawObject() is empty because we don't need to use this
42 handler to paint images: they get put into scene graph nodes instead.
