Registers a private structure for an instantiatable type.
When an object is allocated, the private structures for
the type and all of its parent types are allocated
sequentially in the same memory block as the public
structures.
Note that the accumulated size of the private structures of
a type and all its parent types cannot exceed 64 KiB.
This function should be called in the type's class_init() function.
The private structure can be retrieved using the
G_TYPE_INSTANCE_GET_PRIVATE() macro.
The following example shows attaching a private structure
MyObjectPrivate to an object
MyObject defined in the standard GObject
fashion.
type's class_init() function.
Note the use of a structure member "priv" to avoid the overhead
of repeatedly calling MY_OBJECT_GET_PRIVATE().
