Using `GdkPixdata`, images can be compiled into an application,
making it unnecessary to refer to external image files at runtime.

`GdkPixbuf` includes a utility named `gdk-pixbuf-csource`, which
can be used to convert image files into `GdkPixdata` structures suitable
for inclusion in C sources. To convert the `GdkPixdata` structures back
into a `GdkPixbuf`, use `gdk_pixbuf_from_pixdata()`.</doc>
