Gets a property of an object.
The value can be:
- an empty gobject.Value initialized by G_VALUE_INIT, which will be automatically initialized with the expected type of the property (since GLib 2.60) - a gobject.Value initialized with the expected type of the property - a gobject.Value initialized with a type to which the expected type of the property can be transformed
In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling Value.unset.
Note that g_object_get_property() is really intended for language bindings, g_object_get() is much more convenient for C programming.
