The attached wmf file is rendered incorrectly by the
libwmf gdk-pixbuf loader. wmf2eps, on the other hand,
does a reasonable job. although the eps is stretched
vertically. wmf2gd conversion to png makes a 51x51 pixel
thumbnail, of which all but 20x31 pixels is whitespace.
What you get through gdk-pixbuf is this thumbnail,
scaled up if the application tells it to.
