    icontheme: fill correct information when loading GResource-backed GIcons
    
    When loading a GResource-backed GFileIcon into a GtkIconInfo we
    currently fail to populate the is_resource private field.
    Also, since is_svg is set by looking at the filename, and
    g_file_get_path() returns NULL for a GResourceFile, is_svg was always
    FALSE.
