In addition to informing the session manager of the .desktop file so it can present localized names and an icon in session listings and the splash screen, this also calls set_application_name and set_default_icon_name (or set_default_icon_from_file) if the Name and Icon keys are present, respectively.
If a relative path to the file is provided, this function will search the standard application directories as specified by the <ulink type="http" url="http://standards.freedesktop.org/menu-spec/latest/">XDG Desktop Menu Specification</ulink>.
