Caolán McNamara 397f5daa85 tdf#151898 if svgs are used in hidpi get a high quality GtkImage
this gets nice sidebar icons in this case

as far as I can see only gtk_image_new_from_file (or
gtk_image_new_from_resource) can support the use of a scaleable input
format to create a hidpi GtkImage, rather than an upscaled lodpi one so
forced to go via a file here
