void set_search_path(array(string) path)
//! Sets the search path for the icon theme object. When looking for an icon
//! theme, GTK2+ will search for a subdirectory of one or more of the
//! directories in path with the same name as the icon theme. (Themes from
//! multiple of the path elemets are combined to allow themes to be extended
//! by adding icons in the user's home directory.)
//! <p>
//! In addition if an icon found isn't found either in the current icon theme
//! or the default icon theme, and an image file with the right name is found
//! directly in one of the elements of path, then that image will be used for
//! the icon name. (This is a legacy feature, and new icons should be put into
//! the default icon theme, which is called DEFAULT_THEME_NAME, rather than
//! directly on the icon path.)
