gobject: Add GProperty
Dealing with GParamSpec is tedious and less efficient than necessary;
property definitions should be able to either directly access a struct
field or specify the accessors pair that control a property. On top of
that, most of the property and accessor definition can be autogenerated
from simple pre-processor directives.
So, here's to you GProperty.
GProperty is a GParamSpec sub-class that encapsulates all the types
inside a single, opaque structure (to avoid leaking out implementation
details); a GProperty can access the structure member holding the value
of the property, or invoke the accessor functions passed to its
constructor. Type safety is maintained through the GType system and
without having to use GValue.
Along with GProperty, this patch introduces a series of macros for
automating the declaration and definition of property accessor functions,
and for automating the collection and lcopy of values without going
through GValue.
GObject will recognize whether a GParamSpec used to set or get
a property is really a GProperty, and thus will shortcircuit most of
the GValue-based marshalled code, preferring the direct C function
and direct argument collection instead of boxing/unboxing of GValues.

+ * SECTION:gproperty
+ * @Title: GProperty
+ * @Short_Desc: Property definitions for GObject
+ *
+ * #GProperty is a type of #GParamSpec for defining properties for #GObject.
+ *
+ * The main difference between #GProperty and #GParamSpec is that #GProperty
+ * enforces a specific set of best practices for accessing values exposed
+ * as #GObject properties.
+ *
+ * #GProperty uses direct access to the fields in the instance private data
+ * structure whenever possible, and allows specifying accessor functions in
+ * cases where it is necessary. For direct access to the private structure
+ * members, #GProperty will assume that the instance structure contains a
+ * pointer to the private data structure as its last member, e.g.:
+ *
+ * |[
+ * typedef struct _TestObject TestObject;
+ *
+ * struct _TestObject
+ * {
+ * GObject parent_instance;
+ *
+ * TestObjectPrivate *priv;
+ * };
+ * ]|
+ *
+ * #GProperty is strongly typed, both at compilation time and at run time.
+ *
+ * Unlike #GParamSpec, there is a single public #GProperty class with various
+ * constructors; all public #GProperty methods operate depending on the type
+ * handled by the #GProperty.
+ *
+ * The #GParamSpec methods can be used with #GProperty transparently, to
+ * allow backward compatibility with existing code that introspects #GObject
+ * properties through the #GParamSpec API.
+ *
+ * <refsect2>
+ * <title>Using GProperty</title>
+ * <para>A typical example of #GProperty usage is:</para>

+ *
+ * /* identifiers for each property in the array */
+ * enum { PROP_0, PROP_X, PROP_Y, PROP_WIDTH, PROP_HEIGHT, LAST_PROP };

+ * <title>Auto-generating setters and getters</title>
+ * <para>Similarly to the #G_DEFINE_TYPE macro for defining a new
+ * #GObject type, GObject also provides various macros for
+ * auto-generating the accessors pair of functions.</para>
+ * <para>The most simple way to define a setter and getter pair is
+ * to use the #G_DEFINE_PROPERTY_GET_SET macro. This macro generates
+ * a getter and a setter using the type name, the type of the
+ * property and the name of the property, for instance:</para>
+ *
+ * |[
+ * G_DEFINE_PROPERTY_GET_SET (TestObject, test_object, int, x)
+ * G_DEFINE_PROPERTY_GET_SET (TestObject, test_object, int, y)
+ * G_DEFINE_PROPERTY_GET_SET (TestObject, test_object, int, width)
+ * G_DEFINE_PROPERTY_GET_SET (TestObject, test_object, int, height)
+ * ]|
+ *
+ * <para>The generated accessor pairs will use the #GProperty API
+ * to validate and access the property value. It is also possible
+ * to separate the setter and getter generation by using the
+ * #G_DEFINE_PROPERTY_GET and #G_DEFINE_PROPERTY_SET macros.</para>
+ *
+ * <para>If either the setter or the getter functions require additional
+ * custom code to be added to the auto-generated one, it is possible to
+ * use the #G_DEFINE_PROPERTY_GET_WITH_CODE macro and its sibling, the
+ * #G_DEFINE_PROPERTY_SET_WITH_CODE macro, for instance:</para>
+ *
+ * |[
+ * G_DEFINE_PROPERTY_GET (TestObject, test_object, int, width)
+ * G_DEFINE_PROPERTY_SET_WITH_CODE (Test_object, test_object, int, width,
+ * test_object_queue_resize (self))
+ * ]|
+ *
+ * <para>The WITH_CODE variant of the setter will define the "self" and
+ * "value" variables for the instance and the new value respectively; the
+ * custom code will be executed only after the value has been set.
+ * For the WITH_CODE variant of the getter, the macro will define the
+ * "self" and "retval" variables for the instance and the returned value
+ * respectively; the custom code will be executed before retrieving the
+ * value of the property to be returned.</para>
