-// A specialized container, which is a cross between a GtkBin and a
-// GtkFixed. This container dervies from GtkBin and the implementation of
-// gtk_container_add() is the same: only one GtkWidget can be added through
-// that interface. The GtkBin portion contains normal content and is given the
-// same allocation that this container has.
-//
-// In addition, any number of widgets can be added through the
-// gtk_floating_container_add_floating() method, which provides functionality
-// similar to a GtkFixed. Unlike a GtkFixed, coordinates are not set when you
-// gtk_fixed_put(). The location of the floating widgets is determined while
-// running the "set-floating-position" signal, which is emitted during this
-// container's "size-allocate" handler.
-//
-// The "set-floating-position" signal is (semi-)mandatory if you want widgets
-// placed anywhere other than the origin and should have the following
-// signature:
-//
-//   void (*set_floating_position)(GtkFloatingContainer* container,
-//                                 GtkAllocation* allocation,
-//                                 gpointer userdata);
-//
-// Your handler should, for each floating widget, set the "x" and "y" child
-// properties.
