  * @short_description: A mechanism to wrap opaque C structures registered

  *     by the type system

  * @see_also: #GParamSpecBoxed, g_param_spec_boxed()

  * @title: Boxed Types

  *

  * GBoxed is a generic wrapper mechanism for arbitrary C structures. The only

  * thing the type system needs to know about the structures is how to copy and

  * free them, beyond that they are treated as opaque chunks of memory.

  *

  * Boxed types are useful for simple value-holder structures like rectangles or

  * points. They can also be used for wrapping structures defined in non-GObject

  * based libraries.
