Sets the search path for the icon theme object.
When looking for an icon theme, GTK will search for a subdirectory of one or more of the directories in path with the same
name as the icon theme containing an index.theme file. (Themes from multiple of the path elements are combined to allow themes to be
extended by adding icons in the user’s home directory.)
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 legacy
feature, and new icons should be put into the fallback icon theme, which is called hicolor, rather than directly on the icon path.)
