public static Texture from_resource (string resource_path)
Creates a new texture by loading an image from a resource.
The file format is detected automatically. The supported formats are PNG and JPEG, though more formats might be available.
It is a fatal error if
resource_path does not specify a valid image resource and the program will abort if that happens. If you
are unsure about the validity of a resource, use [ctor@Gdk.Texture.new_from_file] to load it.
