A wrapper for Granite.AsyncImage.set_from_gicon_async to display an icon name.
This is a convenience method for setting an icon name with a desired Gtk.IconSize. Note that you'll not be able to change the icon size afterwards with Gtk.Image.pixel_size or Gtk.Image.icon_size . You will have to call one of the Granite.AsyncImage set_from_ methods to change it's size.
See Granite.AsyncImage.set_from_gicon_async for more details.
